So I've looked at a number of the recipes on here for 460s. I'm wanting to keep this 72 F100 as a driver with some spirit so 400-450hp range. I have a few options available. All bolts going to be ARP and balance the motor. I have a set of D0VE heads that I'm going to go bigger on the exhaust valve and have them cleaned and opened up. I'd like my CR to be around 9.5. If I zero deck, and use 15cc HE pistons, that's around 10.9:1 if I got the numbers right. I'm not sure what's best combo. Stock relief pistons, zero deck or 15cc pistons and don't deck the block. I'm not sure which gives the best quench. Next, I have an edelbrock performer intake, and from what I read, RPM Airgap is better but not sure if it's worth buying when I already have a performer. I have a recurved HEI distributor that's brand new for my 400 which will bolt on. As for the cam, I need to give some background. Plan is to put a roller cam and rockers in. My concern is, I have a strong 400 with an E4OD and 3.55 gears in my 79 f100, and I found that the engine lugs at 60 mph when in overdrive. I found a low mileage 6R80 trans and the adapter kit from PA. The 6R80 has a taller final OD, so I think Im going to need to keep my power band a little lower. I'm unsure of the rear gearing as the tag isn't readable, but I'm fairly certain it's 3.55. It's a 9" so not too hard to pull the 3rd member. I need to reseal it anyway. I'm thinking 3.73 is probably a much better choice anyway. I have read that the RV cam is the way to go, and I've also looked at multiple cam grinds that all seem like good choices. Can I get some input/opinions?
