Guys I need help choosing a cam for a friend. She has a 69 327 461 heads ,stock motor being rebuilt. The motor is going back in her 29 ford pickup. Not sure of the gears, but it runs a powerglide trans. 600 holley . haven't picked an intake yet . She wants to keep her ram horn exhaust manifolds. She hit something and lost the oil, anyway We want to give it a good sound . I am so confused! It will be a driver on pump gas. She's a newby!!! I think she spun the tires once. That put a grin on her face.
Ditto Many will say the L79 cam is inferior to the new profiles, sure if you are trying to wring out those extra few hp numbers, probably not the case here, at one time, Crane had a "blueprint series" cam that included the L79 version. The 268 Comp Cam in the 350 in my 66 Suburban was about the sweetest hydraulic cam I've used.
Comp Cams makes an L79 "Nostalgia Plus" clone hydraulic cam that I will be using in the Arin Cee Roadster and in the yet-to-be announced '32 roadster project. Both engines are similar 327s. The more nostalgic Arin Cee Roadster has the popular cast iron 882 heads with 1.94/1.50 valves while the '32 will get the new production aluminum 2.02/1.50 heads. Both will have 9:1 compression ratio, cast iron exhaust and modest carbureted intake systems. Both cars will be stick shift (Muncie / T-5 respectively) with 3.78 rear gears (early Ford / Winters QC) for fun and reliable street use on pump gas. I have done a lot of homework and think this is the best all-around compromise for a light roadster and the exhaust note can't be beat! Good luck with your project.
Yes, I have been told 268. I been looking at a CS 268H-10 1,500-5,500 it's a454/454 268/268, but then I read it works best with 8 to 1 or 9 to 1. I was thinkint that one and then I get a call from a friend who says go with a Xtreme Energy 218/224 but that is 462/469 308/313. then I read not to go over 450 lift with all stock parts.
Talk to the engine builder, make sure they aren't using cheap rebuilder type pistons which will put them .020 deeper in the bore. All the above cams will do what your looking for.
Nor would I recommend using a higher than stock stall converter (1,800 - 2,000 rpm) in any street-driven hot rod unless you absolutely have to. They are a royal pain in the butt in normal daily use, especially around town with lots of stop and go traffic. I didn't see that your friend's car is an automatic, my discussion was about my own cars, both of which are sticks, so what would work for me might not work for your friend. I agree with Comp Cams recommendation of a milder cam if a stock converter is used. I have had a car that needed a high idle speed mixed with a stock converter and it was miserable in daily use. So...follow the cam manufactuer's advice, not mine. .
Most GM cams folks here suggest came is manual trans cars and I’ve used both with 4 speed cars and loved both of them. RV cams in the 250-260 duration were for auto transmissions. A 29 pickup closed or open is a fairly light car. A stock 300 hp cam with 4-6 degree advance will be a great street performer if you keep a smaller 4 barrel even a spreadbore because of the primary barrels and will get good fuel milage. Good luck.
The "30-30" camshaft was used in 1964-69 high performance 327s and 350s with 11:1 compression and four speed transmissions, along with steep rear gears. 30-30 cam+Powerglide=no low end and a 0-30 time that a '60 VW could beat. If all you want to do is impress the kids at the Tastee Freeze with the lumpy idle and valvetrain noise, go ahead, but if you actually want to enjoy driving the car, there are much better options.
