Should be easy to shorten shifter. My Ford tranny looked like a truck shifter until I took the angle grinder to it. Then rethread to shift knob of your choice. Shortened the throws real nice too.

Jim, 'cept thisin got rubber n-it and sheet meatal r-ound it. I do "stinky" welds with-out rubber. Probably a non-issue till I do a first in-car mock-up.  I suspect I'll learn to say..."this car rips".  roverman.

I've seen that kind before. I think the V6 guys take the S-10 one apart,shorten and put back together. If not on this board maybe the MG Experience board. I think, Bill Young maybe. I'll do a search.

Art, Supra short shifter off Ebay $160. I couldn't find the thread, but some Mazda guys use a torch to melt the rubber out,shorten and fill with hot melt glue so outer shroud doesn't turn.

Jim and clan, think I might be missing something in "Grannys". I could'nt find a link about rear ends. I  don't think mine has the 8" ring gear, probably non-turbo. I'm tempted to try it. Retro a stronger pumkin later ? I have a 10.5" Centerforce clutch assem.,with "marcel" in the disk, should be adequate. Lead on a alum. flywheel, or lightweight steel ? Considering using "scales", for if/how much, to move front wb. I want close to 50/50. HR. mag had a 2 pgr. on hi-dollar 427, side oiler, Tiger-could have been, clone,(had Shelby, the time, in the day). Track car only, and they "rave" about the handling, maybe compared to a regular Tiger ? I'm looking for less"fear-factor", and more overall performance, corners, stopping and road use. Time will tell, roverman.

Roverman, The info on RX7 rears is near the bottom of the page on this link in general info:http://grannys.tripod.com/mainpage.html

Jim, WOW...wow !  Sooo, the 7" ring gear woun't "quite hold", 998hp/1180 ft. lbs. and "only" 9.03 in 1/4 ? I must try it. Healey should weigh-waay-less.Thanks, roverman.

Art, I agree on the dual pattern cams being unecessary for the good aftermarket heads but, sure help out with the stock heads(Ford and Buick and Caddy) puny exhaust ports. Woops. Should have posted on serious cams thread. Where's Nic anyway, I don't want to be the only cross poster.

Where indeed, is Nic ? Last I heard, the Weiderholderer?, family was headed to sunny CA. We haven't been having too many alien abductions, out heer, lately, sooo ?  Paul, what about these,"lumpy bumpies", I'm tryin to un-load ? Oops, now I'm a cross-poster, better than a dresser, roverman.

Ok, 26" tire,4:10s out back and a Supra R154 box, .753 od . I think I need more cam, for max power around 7k. ? Current mech. roller is single pattern, 226 deg. @ .050", 110 lc. and .446" vl. with 1.6/1 sbc. roller rockers.Thought is max hp. in 1/1 4th. and near max torque in 5 th. for, O' blessed mother of accelleration ?  Anyone ?  roverman.

Too thin ? I think so. Standard bore,Magnum down to .105" wall.sonic tested), on non thrust, with planned .03"over bore, I think not ! Reportedly,"all" these blocks are, "nickle fortified". May have to go with,71'-74', pre Magnum,(reportedly thicker walls),w.o. oem. roller cam benefit. 340 block, a pricier option. Race block, way too expensive, roverman.

Art, There are more and more newer Hemi's popping up in junkyards. Would bolt right up! Do a nation wide search on car-part.com. I checked for you. A whole page between $1000-$1450. I wonder if they are thin too.

Jim and clan, your input is well received, but for this project, I want "period correct" apppearance.This car is about, what Chysler/Jensen, "could" have built. I'm already getting flack, for messing-up a rare classic,( obviously not in this forum). If/when I were to install a "HemI" in one of my misfits, it would need to be on top of a Rover block.The 318,(Jensen Healey Hellfire), baseline motor, will have easy 400 hp. and adquate adrenaline attached, to get started on the sorting-out process.  Thanks, roverman.

Calvin and clan. Impressive engine and used prices are falling comparable to LS motors.Basic dim's. comparable to a 318 with 360 crank and "smart", hemi heads.533lbs seems a "little" heavy for alum. heads and plastic int. One problem for swapping this motor into cars that must be smogged, some states,76' up, CA. for one,you must meet visual inspection and road dyno emissions. 75' and prior engines/cars, most states, no problem. I'm considering, best of both worlds, a smart hemi, aftermarket head design in  a bolt on conversion of the LA/Magnum sbm's. roverman.

Clan, Just ran Comp Cams, "camquest 6", program to pick a std. available cam. Build: 5.2L Magnum, Edelbrock Performer RPM heads, single plane with 750 cfm. Thermoquad, 10/1 on gas,small tube headers w. mufflers,2,500 lbs., street/strip use. It said use grind XR274R(mech. roller). It predicts 524 hp.@6,500 and 468 ft/lbs@ 5,000. If this is even,"close", I'll need a change of under-alls ?  Dan Jones/anybody ? roverman.

With the benefits of the HIP. process, I shall attempt to "shrink" a hemi head onto the LA and Magnum sbm. Don't order the lobotamy-jus-yet. roverman.

Art, are you saying that you plan to take a hemi head, heat it to 975*F and pressurize it with 15,000psi of argon in the hopes of shrinking it down to the sbm bore centers? (where do you find 15,000psi argon?)

Now THAT is some radical thinking.

JB

Hey Jim, I think Art already tried shrinking the head with unexpected results.
Just kidding Art. If something like that would work, oh mamma couldn't we have some fun!
Rather than mess around Art, I have a 511ci 780hp bbm in my Jensen Interceptor. If we dropped it from around 8 feet into the healey it just might fit.
Cheers
Fred

Jim, Let's not blow this out of proportion...It's only 970F. Company is called "Kittyhawk,"(Wright Bros')? Garden Grove,Ca.Using retired gun barrels from battle ships(pretty strong).Fred, no Hemi in a Healey, it's for the noisy Cuda'. My Healey wants' to carve some "corners" against your LandYaught , on the inside, a good idea. lol., roverman.

Jim, thanks for the suggestion. Spotted a bare set of "Arias", asking $ 485. "IF", this works, I think we know what,series of motors, would be next project ?  roverman.

Jim and clan, plan is to "squeeze" a junk, sbc alum. head, to make it-you guessed - a "shrunken head". lol. for more hp. roverman.

So I'm guessing they pressurize the chunk of gun barrel (breach with welded plug in short barrel section) with about 2500 psi argon, chuck it in the oven and let the heat generate the rest of the pressure from expansion of the gas?

Are you doing anything to seal the pores of the aluminum? Copper plating maybe? Make a "copperhead" engine!

JB

No copper-too heavy, lol. Maybe more correct term is the inert gas,(sucks-out) the porosity? Don't know/care, just take out the air(pores). A billet head with coollant passages. How "cool" is that "  roverman.

Okay, this is too damn funny.

Whatever happened with this 'shrunken head' idea, Art?

I'd love to see the results, all you really need is a gun breech big enough to take the bare head, an oven big enough to hold the breech which can get up to 1000° F, and a fresh bottle of argon. Seems easy enough. The cast aluminum isn't fully dense so there are internal voids evenly distributed.  That temperature should have the aluminum in a near-plastic state. By the time you shrank it it would be roughly equivalent to billet material in terms of density and strength.

The reason I suggested the copper plating was to seal the voids that were close to the surface to make the shrinking more uniform. Just a few thousandths would do that, and it could be electro-chemically stripped off afterwards. Any competent plating shop could handle that.  (Though wouldn't it look cool to have copper plated heads?)
