400 w/ 7.4:1 SCR

Thanks for all the input guys!



Yeah, I've been following your 400 build for sure. Thanks for documenting it in such great detail! I'm still on the fence on whether to toss in a mild cam or not. What valve springs are you running? My 400 does have a factory 4 bbl intake and I've got a Proform 650 DP and Holley 80457 (600 VS) I can use. I figure since its opened up, I might as well toss in a timing chain.

First things first, I'll degree the cam that's in it now just to confirm what it's got and go from there. The current cam looks to be in great shape, and it's a relatively low mile rebuild so there's small chance it's not stock.

When I build the 470 for it, I'll be building a set of long tubes and 3" exhaust.

For now with the stock 400, I'm just going to build a set of log-style manifolds - quick and easy style. I'm running an engine plate and mid plate, so factory manifolds aren't an option unfortunately, due to clearance issues. I've already got some header and collector flanges, 1-3/4" tubing, 2-1/4" tubing and a couple cheapie flowmaster knockoffs.



Thanks! I followed that thread when he made that thread and completely forgot about it.



Thanks! I've never used those before. Do you spray them with copper sealant, or install them dry?
So u have a forged steel crank in there or just the dampner? Kim
