Title: cast iron 300/340 heads
Post by: roverman on April 24, 2009, 11:25:31 AM

Hi, I'm race prepping a pair for 4.6 Rover in TR7 for 1/8mi. drags using E85 fuel. Trying to make at least 120 cfm. @ 10" on intake side. Flow "flatlines" at 106 cfm. from .400"/.600" L. I believe I read Tim Lanocha was making 280 rwhp. with these heads? Also, anyone versed with retrofiting Lotus 907 heads on the Rover? I've done preliminary mock-up but would like to hear others work in this area. Any skilled contributions are welcomed. Thanks, Art.

If you're after performance rather than Bling, and you can afford to wait until early next year, TA Performance is working on a Rover head that is an offshoot of their highly successful Buick V6 head design. The flow numbers are up there, fairly detailed discussion of it in in a thread on this site.
