Here’s a question you probably haven’t got before in your Ask Away! segments. I have a 0.060-over 283 that is now at 292 cubic inches. I just finished the short block and all my friends are telling me to put a big set of heads on this to help it make power. I can get
Q: I have a 1981 Pontiac Firebird with a Chevy 350 in serious need of some more low-end power! It has a Holley Dominator manifold and a 750 cfm car, 305 heads, a .480”-lift cam, Hedman Hedders into a 3” Flowmaster exhaust, a Powertrax limited-slip differential with 3.73 gears, and a TH-350 tranny with 2,200-2,500
Editor’s Note: This is the second half of an article on how to interpret cam specs to select the right cam for your engine and vehicle needs. You can read the first half here: Comparing Camshafts: A History of Camshaft Specs and Choosing the Right Cam. … Most of us know the four strokes of an
Have you ever wondered why one camshaft makes more power than the other? Would you like to compare the behaviors of multiple cams without ever doing a cam swap? Written descriptions of idle quality, power range, compression, gear, and converter requirements only go so far when the same cam fits in a 283 or 406
Q: Help! I have a 1966 Ford F-100 pickup with a transplanted 5.0L from a 1991 Mustang and the following mods: Ford Performance cam (220° duration/.498″ lift), Airflow Research CNC-ported 185 cylinder heads, Edelbrock Performer intake manifold, Holley 600 cfm carb, B&M flexplate with a 50 oz. balance, TCI C-4 Street Fighter transmission, and a TCI
I’ve heard there is a really good factory LS intake manifold out there for cathedral port intakes but the friend who mentioned it didn’t know anything more than that. He said it was from a truck or an SUV but he wasn’t sure. Do you know what he’s talking about? I have a ’69 Chevelle
Q: I would like to install disc brakes on all four corners of my ’69 Camaro. It’s currently equipped with drum brakes, and they’re just not doing the trick. I’m wondering if the suspension from a C4 Corvette can be made to work on a unibody vehicle. I think this would be a cost-effective way
I would like your opinion on my ‘61 Comet 2-door wagon. It’s a car that will be used for local cruise nights and Friday night street-legal drags. My question is how much horsepower would I need to get into the mid 12-second range? I see all sorts of online estimators but quite frankly, they
When a camshaft is “degreed” it means the camshaft position in the engine has been synchronized with the crankshaft position. Degreeing the cam is the only positive means to determine if the rise and fall of the pistons correctly matches the opening and closing of the valves. Several degrees of misalignment can have a profound
Q: My 1967 GTO has a 455 Pontiac powerplant with Edelbrock 87cc heads, .030 over Ross pistons, Total Seal rings, Eagle rods, a Crower cam (int./exh. duration 248°/252° @ .050″, lift .512″/.524″, lobe separation 112°), 1.5 ratio rocker arms, and Clevite bearings. The engine was shop built and balanced, and is also equipped with an
