Hello,
I am new and am looking for good advice.
I have a 1976 Chevy Nova with a stock 305 2 barrel 308 rear end. Its an old car from High school I have had setting in my shed. I have been in the process of body work. She has 101,000 miles all stock. With two children I am on a budget. I want to get some more HP out of the 305. This car will be used as a toy seeing street use. I know the 305 and 350 have the exact valve springs. The 305 has a intake valve lift of .3727 and the 350 has .39. The exhaust are the same. I don not want to change valve springs. How much cam can I use with stock springs? My first choice is Howards Cam Camshaft, Hydraulic Flat Tappet, Advertised Duration 280/288, Lift .390/.410, Chevy, Small Block Summit part number HRS-112701-12. My second Choice is Summits cam Hydraulic Flat Tappet, Advertised Duration 278/288, Lift .421/.444, Chevy, Small Block, Kit part number SUM-K1102. Can the stock springs take the extra lift with the summit cam? Will The valves clear the piston with the summit cam? My gut tells me to error on the side of caution and use the Howards cam even though it cost more + lifters. I am going to still use the stock converter. Also do most people reuse the old cam bearings? Thanks,
