This might not be the most exciting topic, but I'd still like to get your opinion on this.
I'm building a 289-2V for my father-in-law's 65 'stang. I'm going to convert it from a 6 cyl A/T to a V8 A/T w/ P/S. He's 76 so his interests lie in reliable economical performance...not max power.
He'll be giving this car to my son one day, so I'll be working on it for the rest of it's life. I've got all the parts to build a stock motor with long tube headers.
My questions to you are for your opinions on the heads, cam, and exhaust. I've got three sets of heads, C6 - 289, C8 - 289, and some as yet unidentified 302 heads that came off my **sick** truck motor. I'm planning to use cast flat tops, or if the block doesn't clean up until it's bored 0.060" over I've got a set of cast dished 0.060 over pistons. The C6 - 289 heads have smaller combustion chambers than the C8's. And, they
(C6's) should yeild a good squeeze with the flat tops. I imagine the 302 heads have the largest comb chamber of them all (haven't taken them off the block yet...so I don't know what they are). I'm going to run a 2V intake and a 2bbl carb that I already have. I have the stock cam and lifters that came out of my donor motor (the one I built for the truck recently). And, I would consider buying a new cam and lifters for the car based on your opinions...but I'd rather not. As for the exhaust, I've got a set of Hedman (I think) long tube headers and I'll have to build the exhaust. I'm planning to use 2" tubing with an H-pipe and duals out the back. What mufflers should I use, it needs to flow good, but can't be loud
? If my mother-in-law won't ride in it, then I've failed to meet his expectations.
So, in summary:
1) Which heads should I use (assuming they will all consume the same amount of $'s at the machine shop)?
2) Will the stock cam deliver the most economy on this set-up (assume 3.00 or 3.25 final drive gear)?
3) What exhaust system design (tubing size and muffler selection) will yeild a quiet and economical (MPG not price) package?
Thanks for your consideration of this rather boring topic.
