head cam swap,rocker rebuild?

**bpopham22** · 07-28-2011, 04:06 AM

Ok heres the plan,I'm going to order my prc stage 2.5 heads along with the comp 212 218 high lift cam. Should I have the rockers rebuilt for the new heads or can I use them as is? Car has 95xxx miles on it.

what are the cam specs? It should be fine to reuse them just torque them in right.

Two things...

1. That is a REALLY small cam...I would at least get a 228R cam to take advantage of those heads. Personally, I'd get a Torquer V2 cam...I loved mine with my Ported/Milled 5.3L heads.

2. I'd get the Trunion bearing upgrade for your stock rockers. I got it for my stock rockers (77k) and I'll be using them on my 427 LS3.

Your stock rockers will be fine. I don't think you'll be happy with that cam. It is the same one I started out with and it was a total disapointment. I was changing it out for a Torquer V2 within 2 months and very happy with the outcome. When I added stage1 243 PRCs later it picked up 50 rwhp on the dyno. A TV2 with Stage 1 243 PRCs pulls hard thru its power band. Stage 2.5s might be overkill. The cam your talking about putting in is about the same as a stock Vette cam.

I know its a baby cam,that's what I want.(keeping stock converter till my tranny shits out) I'm gonna have to look up the trunion bearing upgrade.

A cam install is no small feat...you'll have to remove the radiator, water pump, crank pulley, front cover, oil pump, timing chain, remeasure the push rods for correct length, then get a retune for the new cam.

I'm telling you now, putting that cam in is a waste of time and money. I 100% guarentee, you'll be VERY disappointed that you're time and effort got you sub 400rwhp numbers.

Yes x1000. I have a 228r in mine now and wish I would have gone bigger. 228r should be good for a stock stall though if thats really what you want but if I had an auto a good stall would be my first mod.

I know its a major deal that's why nelson performance is doing it for me. I want a stock like cam with dd properties.

This makes it sound like you shouldn't change out the cam at all.

I had no problem driving my Torquer V.2 cam on the street. If you're worried about it not driving stock, then drop down to a 228R cam. If you want it to sound like stock, then get a high LSA, like 114 or 115. There will be no choppy-ness and you'll have the power you want.

listen to ls1camino. I have an m6 with a tsp 233/239 camshaft and my car is a DD. I have no problems driving it when it comes to the cam, now the clutch is a different story. I dont even know why you would even consider doing all that work and spending that money to put that cam in, thats like taking your ls1 cam out and putting a ls6 cam in. Waste of time and money imo, the smallest cam id go with a 228r ATLEAST! Especially if youre buying heads too.
