Upgrading to a Hotcam, need to know about RRs and Springs

My car is in my garage right now dismantled.

I have bought Longtube Hooker Headers (with no o2 Sensors, so i am f 'ed there), and ported and polished heads.

I also bought a LT4 Hotcam.

With the Hotcam, i heard i should upgrade a lot of things. I have weighed the facts, and have bought a new timing chain and am going to buy upgraded Springs and upgrade to 1.6 roller rockers.

I have allready put a lot of money into this massive project and am asking for you guyses advice.

What is the best value springs and 1.6rr's that i can buy in my situation. Not the best ones, the best priced ones.

Re: Upgrading to a Hotcam, need to know about RRs and Springs

I just bought the LT4 Hotcam Kit that came with 1.6 RR's, and LT4 valvesprings.... On a side note, i would do lifters too. People told me i didnt really "need" them when i did my install so i didnt put them on there... BUT, one of my lifters is collapsing on my driver side now so i have to buy some Comp R lifters to replace them.... Only telling you because i wish somebody would have told me Good luck.

You don't have to get FULL roller rockers. You can get roller TIP rockers for a bit less than full rockers. I saved my money until I had the extra $100 for full roller rockers just because I had a feeling I would have wished I had waited 'till I had the money to get the full rockers. But it really wasn't all that necessary.

I have looked there. This project is getting more and more expensive.

The stock springs can't handle the lift on a Hotcam. Save yourself the heartache and at a minimum get the LT4 springs. You can get the entire LT4 spring kit (shims, keepers, etc.) for ~$60 from Jason Cromer.

Definately get the retainers.I didn't and it cost me an engine (dropped valve). Get the LT-4 valve springs too and the new keepers that go with the new retainers.
