fellas i'm trying to figure out what cam would be best. i'm building a 351w for my truck it's going to be a roller block bored 30 over with gt40 heads, a preformer intake and 600cfm carb, shortie headers with a C4 trans with 3.55 or 3.73 gears on 28 inch tires. my question is what cam do you guys think would work best. it'll be a daily driver no towing or hauling now but who knows what's down the road. i want the power that's why i'm going 351w.
oh! well i'm starting from scratch! i'm buying a 351w shortblock roller, punched 30 over, i'm getting the gt40 heads as stated above. the truck currently has a 302 stock that is very worn out(farm truck) C4 tranny w/308 gears.. eddy performer intake and 600cfm carb
Compared to a stock 302 this is going to be a monster.. more power everywhere and especially lots more TQ. I just discovered the cam I suggested above is a retrofit cam so you don't want that one, the comp 35-420-8 or similar is what you should be using.
ok thanks for the help. now i'm happy because the builder was offering the b303 cam & i wasn't too sure about that for this build. the gt40 heads will have the 1.6 rockers with new springs and seals (basic clean up). i can't wait to start ordeing the parts when i get home.....
Conanski i just looked up the 35-420-8 & it says that it's for the 302 you were right on with the 35-413-8 for the 351w thanks for the help you're the man!!!!!
302 and 351 motors use the same cams so don't worry about that, the B cam is a bit wild for a truck motor IMO, the E cam is better but neither will produce as wide a powerabnd as the Comp 35-420-8.
wow! that's why i joined this fourm to get this type of info. well now i just got to shop around for the best price for the cam lifter & rods to match the gt40 heads!
well i called the place where i want to get the engine from. he said that he could supply the lifters and cam with a similar grind to the comp cam 35-420-8 for about $240 more which isn't bad. he also went down the list of cams that he offers but he went to fast to write them down. but i'll find out what he has before i order it.
well thought i'd post this info too! i called summit today they reccomended the sumk3600 cam. the grind is close to the comp cam. so what do you guys think? the price is right for a budget $100 with the lifters!
