Thread: A SBC build

Tweet

print out the tech sheet and make some calls to the cam companies! These guys are the experts and all it costs is a phone call. The numbers Pat put up should be close.... I've always had real good results with them, accuracy on the sheet is the most important thing!!!!!

Just a personal thing, and nothing scientific to back it up, but I've never gone over 525 lift unless it was on a mechanical roller....

the cam my friend dave is telling me to get <irony huh?> is something like.
.512 .515 with a shi*load of duration i can get those specs tomorrow hes sacrificing lift, for the durationt hat will carry it to the top end when i got look at the block and crank they are done yes! and the crank got away with a good polish block was also decked .10 or .12 piston will only be int he hole .10 now. with those big domes i am stressing piston to valve clearance!

Make sure you use some clay and check the piston to valve clearance, always used .100 clearance as a minimum...... Don't know if that is accurate for a chebbie or not????

on the sand drag stuff i seen stuff hit when it should of never hit cut the seal right off the guids and hammer the top of the guild s with triples the weight and the spring just can not keep up and starts to jump up and down it just can not hold up then bad things hapen

Yup, the heavy valves and pushrods can make things go bang that have lots of clearance!!!!! (Please don't ask me how I know this! )

yup them trips i put in the sand drag could hold up a train car ? but harmonics and weight they just could not keep up i have pull them out and were a 1/2 shorter on free

yes 100 works that cam that i posted is very old and it at av282/292

i belive it is dave. i am stressing it. this guy has been the local john milner type since the 60's 70's used to get big into the high winder stock cars and drag cars, even used to build monster bbc's for tractor pull's hes done a bit of everything i suppose, was telling me he started at a mechanics shops month later went to nam came home and hasnt stopped on the racing motors since,! just slowed down a little bit, you daves have an ironic past huh?

WELL JUST HOLD ON THERE IT COULD BE YOUR BETTER 1/2

considering the busiest racing season i ever had was 5 races im not to worried about stuff as i am not thrashing it every single weekend the next motor will have the good stuff, might even be a lil bigger :O oh did i lead on to that "evil" 327

it is odd, two daves into racing. hell you guys were probably buddies back then

ha!

Good call.
I had a 67 with a BBC/glide that I bracket raced for two seasons.
Nothing that fast 6.40's but I loved that car.
Both the Ford and Chevy guy's hated me.L.O.L.
