NOlowrider Thanks for the input. You guys are right, oval port. I was looking at the exhaust. Thank you. I think that is the cam (638-00024LK). I am going over to look at it tonight. I seem to having trouble finding a set of pistons that I want. I would like to be around 10-1, or so. Or is that even an issue with the BBC? I have KB hypers in my current build, but I always said that if I could do it over I would change. I have not had any trouble with them, but it is that whole top ring thing.

firestone The 781 heads are good, but BBC is right, they are oval. That is actually a good thing in your case, The rectangular port heads are not beneficial unless you are going to be running high RPM or large cubic inches. I found a little info on the 292. It seems like a fairly well matched cam for your setup. The only down side is that it is a single pattern which is not the best for stock heads. As far as the intake goes, I think a dual plane RPM would match your combonation much better than a tunnel ram. I know people like the look, but as far as a matched combonation, the dual plane is probably best.

Lunati cam

BBCMudbogger Well the first thing is if I read your post right you have 781 heads, but they are not rectangular, but oval ports but should flow pretty well into the RPM range.

BBC 454 combo

Hello everyone. I am beginning to look at building a 454 to replace my 327. I cam across a 454 w/TH400 for a great price (free). It was a running engine when removed two years ago. I am a decent SBC builder, but this will be my first BBC. I am looking for some ideas for building this engine. Have not really decided to build low torque or mid-upper RPM. I really would like to run a tunnel ram w/duals. Block cast #361959, heads 336781. Upgrading the heads is not possible at this time, not enough $$$. It is an retangle port, 2 bolt main. My neighbor will be giving me a Lunati 292 (don't know more than that at this time as I have not seen it yet). Will be going in a 74 Chevy truck, 3.73 rear end. Looking to upgrade pistons, intake, carb and cam. I have a new B&M 2800 stall left over form another project. Thanks guys for any advice.
