Build for a stock 346 - curious to see what it should be making - v. big heads/cam A valve spring was broken on my car and took out a piston and cracked the block... So here's what was done.
99 FRC Corvette
Bottom end -
A stock 346 rotating assembly rebuilt - honed, hot tanked, etc
-new rod, main, and cam bearings
-new rings of course
-all new gaskets
-Ported oil pump
-Powerbond 25% reduction balancer/pulley
Top end -
-MS4 cam
-TEA Stage 2 heads with 58cc combustion chamber and appropriate milling for 11.5-12.0 to 1 static and 8.4-8.65 to 1 dynamic compression ratios
-Comp 921 spring kit
-0.040 headgaskets
-Stock rockers with trunion upgrade
-Hardened pushrods (will have to measure size)
-Ported FAST 102 intake (ported by vengeance racing)
-Breathless intake/duct
-1 3/4 headers and 3 in catless exhaust
I know the pistons will need to be flycut a bit - not sure how much tho, we'll have to measure
It'll also have an LS7 clutch and the car has 4.10s already (won't matter much but I'll say it here anyway)
What do you guys think we'll see out of this?

Haha, I'm waiting on the heads to come back from TEA. Then it'll be a day or two for ECS to measure for pushrod length and flycut the pistons.
Then it'll come home and we'll assemble it, fix any issues, then tune.
Probably 10-14 days total.
