Any chance there is a shop around you with a flow bench?

Yea, there is. Not sure if I will spend the money on them though. Think they charged 60$ to test 1 intake and exhaust port on some 317s a friend rushed my to do, they went 276 cfm on the intake, and we're nothing as nice as these will be but these will max at 280ish at best usually since they do not move air like 233/799/317 castings can with a 2 inch valve, I would need aarger valve with these and I am not looking for max power, just as much as I can make for as cheap as possible yet not trying to make peak power. Still need some low end.

Well, started ordering parts. Edelbrock 2215 cam should be here today. Springs, locks and retainers came in. Need to finish the other head, drop them off for a valve job and mill them .030-.040. Head gaskets are in as well as head studs. Fixing to buy a new millermatic 211 welder, so life is going to get easier. Buying crap is easy, finding motivation to work on it is a issue with all that has happened as of late. But, ball is rolling.

Need to pick up the rear end from Nemess, he is selling me a 2000 model 10 bolt with 3.42. Should be better than the stock rear with less abuse and better working limited slip. Will eliminate the need for rear spacers with 4th gen offset wheels.

Cam came in, it says 220/220 @.050 on the cam card. Pretty dumb since it says 220/224 everywhere else.

Sorry to hear about the 89 but nice replacement. Ive got a 4th gen B4C.

Im ready to hear how the 4.8 does for you in that chassis. Ive got one in my garage I was thinking of throwing in my 95.

You really think so? A 4.8 vs L98?

Thats pretty amazing if it does! Glad I held onto it...

Well, stock for stock, the worst 4.8 made 270 hp, the best l98 made 275 or so. But TPI 5.7 vs my carbed 4.8 setup, I lean to the 4.8. Although the tpi will have more low end tq.
