Haven't bought any parts yet but have a new 6.2l engine L92 heads, leaving bottom end stock.

Going to send the heads out for CNC porting/milling or buy a set outright, going with a 850 carb., staying with hyd roller. rev to 7000. Automatic car for drag race application.

Cam, head, intake recommendations?

Have some ideas, just seeing what has worked for some that have been running the L92s.

Thanks

I hear the Tsp 231/236 cam on 111lsa works well with single planes.

I have a set of TSP CNC'd L92's with the good PRC dual springs that will be for sale soon if you are interested. Heads only have 1200 miles on them worked great, I am going FI so had to make a change.

No way a 255/263 .632 cam will fit in a stock bottom end milled headed l92. Ask me how i know! lol

x2 definitely not with a stock bottom end, flycutting would not even be a choice...... it would be a grenade .....

Nice build! Should make 570 plus hp with the tsp cam.

OOOOOHHHHH. Dats purdy.

You might get away with a mid 230s intake without flycutting, But you want compression too? I'd go something like a 240-250 on 108 with 11:1 and flycuts. 110-112 stuff is a wide lobe sep for single plains. I run 110-112 on plastic intakes 108 on the single plain with a 240s intake.

Best thing you can do is get a custom cam cut for your appilication to be sure that all your parts are working together. I just had Goeff at EPS cut a custom cam for my 402ci. Be sure to have all the information about your build and your car handy so he can be spot on with the specs.

X2, nice to hear I'm not the only one to put a 108 LSA on a Ls single plain carb motor.

I just finished a carb'd 402 with around 12.5:1 compression, a single plane, and a custom spec'd COMP solid roller on a 106lsa, 256/262 @0.050 with 0.690 lift. Motor makes all the right sounds.

Sounds good to me.
