I have searched for the answers to the following questions but have found no answers. Please help if you can.
I am running a SBC 350 and wish to improve it's performance. I currently have a mild cam (214/224, .442/.465) that is still uninstalled. I would like to run a slightly hotter cam but don't think it would work well due to a low compression ratio (8.4:1). I also have headers, a 650 Holley double pumper, and a Weiand Xcelerator intake installed. The HEI has also been recurved and had an adjustable vacuum advance intalled and locked out at 12 deg. advance. The pickup weighs 3380 pounds without a driver and has a 3.73 limited slip rear. Transmission is a 350 with a shift kit. Torque converter is stock. This is a semi-daily driver.
I realize that Vortec heads may not be the best but it is a matter of economics and they were given to me by a friend. I would like to install them to increase the compression ratio due to the smaller combustion chamber. These heads came from a late model 350 and are the 906 castings. I have several questions.
1. I have read that you can use a non-vortec intake if you slot the bolt holes. Is this true?
2. Is the Vortec roller cam setup worth using? It seems to be priced right whenever I see them for sale.
3. Where can I find duration, lift, etc. numbers for the Vortec roller cam?
4. If the cam is too mild, can I use another roller cam with the factory Vortec roller lifters?
Thanks for your help.
