Re: camshaft advise

I had an old 350 similar to what you have going on. For the cam, I used a Clay Smith Cams grind C-304-8B. It had the following specs: 304/304 adv., 258/258 @ .050, .525/.525" lift w/ 1.5 rockers and a 108 lsa. It was a great little cam and got my shit going 7.40's in the 1/8th in a 3200 lb camaro.

Also, I ran a summit 10" 3500 stall converter, 4.11 gears in the factory 8.2" with an auburn posi. No transbrake, no nitrous and was my daily driver.

Re: camshaft advise

If your running up to a 3500rpm stall, want good street and strip manners with response and fast times use a 110921 Saturday Night Special lashed at .018"/.018"
280/288 @.020"
244/252 @.050"
152/160 @.200"
.518"/.536"
106 lobe separation

If using say a 4.56 gear and 3000rpm stall, this cam would work great.

If your using 4500rpm stall, go with this cam, 111411, also lashed at .018"/.018"
292/300 @.020"
256/264 @.050"
164/172 @.200"
.545"/.563"
106 lobe separation

seem bout right
