im looking in to a set of head for my 370. the ones are TSP 5.3 stage 2.5. i have never had just a cam and heads setup. what kind of RWHP do you guys think it will make. i might put a shot of nitrous later on down the road. the cam is a 228-232 114lsa.

im looking to make a little over 400rwhp on heads cam and longtubes. what ya think?

 

i think a set of l92s would be very nice for that setup

 

i have 243s milled .030 with a 244/248 .612/.615 112 lsa cam on my 370.

 

Those heads will work out well, but if you're building an engine like that I'd go for a bigger valve setup. The L92 head would be a better choice if you get the compression up to around 12:1. With that cam though the 5.3L heads may be a better choice.

 

for big nitrous or boost go with a thick head deck ( not stock ) but for n/a there is alot of good options with l92 being one of the best for the price.

 

U shud give Richard @ WCCH a call and pick his brain. He'll have a few options for ya...I have All-Pro heads (see pix in sig), and wasn't too sure out of the gate but since discovered they're actually quite good with a good tall deck if u want higher compression NA.

 

i a going to call West coast tomm. and see what they tell me. thanks for all the help and info. for now im going with TSP 5.3 heads and see what they will do.

 

What about Trick Flows?

 

I am building something similar how would that cam behave in a 1500 HD with an 80E? I DD it and tow with it on occasion. I was tossing around what kind of cam for my motor and this one might be a touch big but I wanted to be sure. I too am trying to deside on heads.

 

it worked well im my truck. u can hear it on FD thread. just search dyno 370 radix. or my name 05crew. the next thing is a stall. i had a PI 3200 with the same cam. but i dont want to spend a grand on a stall, what can i do?
