im trying to put together a sbc 350 and im having trouble with cr's dcr's in relation to the camshaft I want to use. Ive heard everything from "no it wont run on pump gas" to " ive ran 12:1 on pump gas" tbh my ears are smoking and im at the point where a guy might sit in his garage drink beer and throw hammers at it. Not really but i am frustrated and cant continue with the build until i get this sorted out. sooooo this is what im working with..... bought a goodwrench 350 in 08 im the only owner so crank rods and flat top pistons are as they came when i bought it. i bought a set of aluminum 64cc heads 160 202's 190cc intake runners and a howards cam retro hyd roller intake/exhaust 264.6 268.6 lift 485 495. the engine is in a 1978 chevy K20 pickup, sm465 manual trans, np205 transfercase 410 gears 6" lift on 35" tires. I use it for farting around town but mostly for long hauls with a 1500lb drop in camper. with onboard water and all gear total weight with the truck 7K to 7500lbs. Anyone care to take a stab at it? Or suggest a good throwing hammer?
