Mgb chassis strengthening ideas

[danielruhe]

Does anyone have any ideas for structural strengthening when doing a v8 conversion? I am putting a very well build 302 into a 74 roadster, and I just want to make sure the unibody is up to handle the 375-400 hp I will be putting in the car.  The last thing I ever want to worry about in the car is completing the project and end up with a twisted frame.  I have already bought upgraded suspension/drivetrain components (fast cars ifs/cce 4 link rear/ford8.8 etc.).  I also have already repaired any rust and added rear subframe connectors from mid frame to the front leaf spring perches now going to be used for the 4 link setup.  I plan on making this car a very nice street car, but also be able to drive it very hard reliably, and potentially take it to a track. Any suggestions would be greatly appreciated!

I like what Geoff did in his build thread:

That's a pretty stout 302 if that's RWHP.  Would love to hear what you're doing to get that.

That is the crank horsepower, haven't built the car yet so yet to put it on a dyno to test rwhp. It is a custom built roller engine with a custom cam AFR heads and lot of other goodies, also might add a nitrous system for the fun of it to get maybe 500 or high 400's.

The MGB is a fairly stout unibody.  What you have already done will go a long ways to making it even stronger.  I also like the additional front outriggers in the link by Jim N.  Someone else did that mod many years ago (can't remember who).  A roll cage will do the most.

More ideas.
