looking for cam advice for a 73 318

Well, the Torker line is a low level single plane intake designed for a RPM band of 2500 - 6500 RPM's. Cams that operate in this area or a healthy cam designed to increase power alot, not alittle bit. With durations that start at or about (Brind dependent, but in general, close enuff) 236* @ .050, you'll need a good jump in compresion in order to get things going right.

That intake is a great "On the cheap" intake to start racing or get a "On the Cheap" read light bandit up and going without cutting up the hood.

The 318 ia advertised at, what? 8-1 or 8.5-1? BUT, if you mic it out, it'll be in the 7-1 area for sure.

Once you install the intake, you'll drop the vacuum signal and the small cam will not be able to pull much. IF Your looking at a bigger cam it will reduce vacuum even more. That cam you listed is barley above stock.

Performance tanks even more since the compresion ratio is low is now made even lower due to the larger cam because of it's timing events. About this time, it's going to be able to run on cheap Vodka or yak piss. It'll feel like a 6-1 ratio. Junk, garbage.

Dollors to douhnuts, a 2bbl. will out run you until the big end, which by then, for you, it'll be to late to catch up. Your sunk and shot down by what you actually started out with.

You'll be offered jeers and sarcastic congards for building a crap combo and highly embarrassed.

Seriously, take the advice of Moper and 1W&CG ! These two guys have been here awhile and I can say, easy, when it comes to doing builds, there good. Moper builds them on top of it. He's in the trenchs of the shop getting greasy. That there in itself is a great reason why you should be following his advice.

1W&CG and myself echo his advice.
