i'm looking at running in a new s-10 truck class and the rules limit me to 320 ci any combo i want does not have to be chevy as long as it's under 320. i have access to a 318 mag w/3spd
302 from a 83 f150
305 from 83 caprice
also have a v6 buick from a 83 cutlas
307 olds from a 84 la sabre
i'm looking for the best bet for a consistent power plant that won't cost an arm and a leg to maintain

I have a friend that runs a 283 sbc bored .030 with domed pistons and .532 lift cam He probably has 1000 to 1500 in it.

Good Luck

If you are gonna run light run the 302 for weight savings, the heads don't flow though. If I had your limit rule I would run the chevy 307, the larger bore will pounce on the 305. Surely you can trade one of your's for a 307, their value is pretty low, then put the small chamber 305 heads on it.

I would run the 305. my buddy had one in his car with a 280comp cam and 750 double pumper and made the trophy dash the next night.It worked really good believe it or not.

Go with the 318 and 3 speed. The torque curve is much better than the others. AND MAGNUM HEADS FLOW OUTSTANDING.

i was thinking about using the 318 but i have no parts like i do for the chevy and have no knowledge on how to make it run like it need to be ran. and isn't a 318 pretty heavy we can't add any weight and the box is gutted already want to keep as much weight off the nose as posible
