Hi!
I am about to upgrade my combo whith some new 195 AFR heads and my question are if i stroke my 355 will the hotcam be to small,the goal are maybe 400 rwhp.
If to small any suggeastions of cam?
How much max hp whith a hotcam?

400rwhp is about the upper limit of the LT4 hotcam... and honestly, its kindof an outdated design. There are much more modern designs out now that will make better power and torque, especially with a stroker motor. Something in the 230* @ .050 range would be a good choice for what you're after!

Ok
So a 230* range at .050 on a 112 LSA and .500 - .525 will be fine even if i stay whith the 355?
Thanks!

What do you like this?

280H( 230 230 @.050, .480 .480 lift 2000-6000 RPM). 1.6rr chould be about .520

A cam about the size would be a good match, but that cam is meant for a carbureted engine. Comp Cams has a listing of cams that are designed to be used with computer controls/fuel injection. One of those cams, of a similar size, would be a better choice.
