The block is a 77. It's going in a w350 with an automatic and 4.10 gears. I want to build a torque motor. Im trying to figure out what cam to use. I was thinking about using the Hughes SEH1620AL-12. The heads have already had appropriate springs installed for big lift. They are 2.02 j heads. I will be running an edelbrock performer intake and headers. Any rough idea on how much power this could make?
I have the SEH1620AL-12 in a 360 built almost the same. It worked good for me. My 360 is 0.030" over, about 9.5:1 compression using the KB-232 dished quench dome pistons, milled block and heads. After messing with those pistons, it would have been easier to just use the pistons you have.
The heads are J heads from Aerohead with the 2.02" intake valves and hardened exhaust seats. They are ported, but I don't know what they flow?
I was using the regular Edelbrock Performer that has the EGR (in case I needed to emission the truck.) I currently am not using the EGR, so the intake was tapped for pipe plugs and blocked off. The performer intake ports neck down to 318 head size, maybe 1/2" to 3/4" from the mating surface. Gasket matching the intake was pretty easy.
I used a Holley 670 cfm truck avenger carb on it.
I had the engine in my '84 Ramcharger with 3.23:1 gears and 30" tall tires. Converter was a stock hi-stall replacement. I used the 360 B&M flexplate and the engine was balanced with it, so I could use any normal balance converter. The converter was OK for daily driving, a bit tight, but that was fine with my gearing.
I rolled the RamCharger the engine was in, so now the engine is awaiting to be installed in a '69 Coronet 500 (318 car) with a 518 trans behind it. If I had the money, I though about having the engine dynoed just to see what it makes? My goal was about 350 HP and 400 ft/lbs of torque?
