im building a strait ls and wanting for 400hp+ and im doing it on a budget....right now i have a built bottom end with eagle rods and 8.8:1 srp i think pistons...wanting to put crowler 404s in it....do u think i should upgrade the springs and retainers...what size turbo should i use for this kinda power goal...and do u think this power goal is possible with what i got and wanting to get....keep in mind im doing this on a budget too...thanks for the input guys...

 

springs and retainers are a MUST for those cams!

 

yea i thought that but alot of ppl just say they put 404s with a good intake manifold and they are making good power...thanks for the input bro ill keep that in mind...

 

bump

 

um you CAN'T just put those cams in without the springs/retainers... it won't work.. you'll mess your **** up

and i used a SC6152e to make 403whp on 18-19psi on my built ls motor

and its CROWER , not crowler

 

ok my bad ha i suck at spelling and do u really think its worth it to go with the crower setup?

 

I made 407 on a customers stock LS motor with a SC61, topmount mani, some regrind all motor cams, and 1000CC injectors on pump gas. @ 24PSI been running for about 4-5 months now, and its still being ragged on daily..

 

The Crower 404's will work great with a good exhaust manifold and intake manifold

 

i was told to run the stage 2 crower turbo cams that i would like the results better than the 404s....any suggestions on that...

Whats your budget?

Cams, valvetrain...LS, 400 hp and Budget usually dont work well together.

Go with the crane turbo cams or the crower 403's or 404's.

I personaly run the crower 404's with a 60-1 p-trim in a .82 a/r housing.

 

upgrade those springs and retainers!!


also get an aftermarket intake manifold. your torque curve will thank you

 

I forgot to mention that I also run the crower spring & retainers with a skunk manifold with a 8400 rpm shift point.
