Vortec setup OR roller rockers?
Hi,
I'm hoping I can get some basic advise here. I have got a few options in my garage and am wanting to get the most bang out of what I have.
I have A 1974 355 SBC two bolt main with flat top pistons
I have some Vortec heads with stock springs, cam and rockers. OR I have some older 882 heads that have the Erson TQ40 cam set up on them: .472/.472 lift with Erson roller rockers, rods ect.
I also have some 305 heads(354434) that I could use and an old 327 cam and the stock cam out of a 76 Malibu.
both setups would have an Elelbrock intakes and 600cfm Carb. I read that the Vortecs are awesome and achieve maximum port flow around .400 lift so if I modify the Vortecs it will be screw in studs and stronger springs only - probably not going to increase the lift. I'm shooting for around 400hp and it will be a street car. (71 Skylark)
knowledgeable help is greatly appreciated.
Thanks!
