I have a stock LT1 that I plan on rebuilding. When I took the motor apart the pistons broke off on the ring lands so I bought a set of new Speed Pro Hyper..Pistons 2v relief and a new set of PM rods..My 1st question would be should I balance the RT assembly and then assemble the motor? Also, I had the crank turned a few months back std. how can I remove the rust that has accumulated on it? I'm gonna do a LT4 cam with LE1 heads, ported intake w/full bolt on's on an M6 Camaro. I know the parts I have aren't the best..but it's better than what some people are running. My goal is to run mid 12's which I know is do-able with work...advice would be greatly appreciated.

 

Take the parts to the machine shop to be balanced, have them decide if the rust is minor enough to be polished - they will measure and can sell you the correct bearings at the same time. Get it done right and professionally now and save money and heartache in the long run.

 

Id donno about that that camshaft. Talk to Mr. LE about a cam to match those heads.

 

I did think about it...the thing is I already have the LT4 hot cam..I'm thinking off the shelf cam, the biggest I'm thinking of using is the CC503 with a small nitrous shot. I do have to drive it to the track and it's gonna be somewhat of a DD.

 

What kinda of bearings do you recommend? I was looking at the Clevite 77 P-series or the speed-pro?
