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
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
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
I have a ’69 Camaro with a 454. I went to fill it with gas on its first run for the spring and drove it perhaps 20 miles. After stopping briefly, it would not restart. The engine sounded like it wanted to crank but turned over slowly. The battery tested 12.8 volts and its only
Q: I own a 1986 Ford Bronco 4×4 with a 302 V8, electronic fuel injection, and a C-6 automatic transmission. The body is banged up and rusted beyond repair. I plan to remove it and install a 1951 Ford F-1 pickup body. However, I’d like to remove the EFI and install a 4-barrel carburetor. Do
This may sound like a simple question, but what is cylinder wall glazing and how is it created? I hear about it all the time when people talk about piston rings not sealing, but I’m not sure what it really is. Thanks. – T.D. … Jeff Smith: Great question! We did a little digging and then
Q: Recently, I purchased a 1974 Chevy Impala 4-door. It’s a pretty big car, so I decided to swap the small block 350 with a big block 454. I had a buddy build the 454, and we got a lot of parts from Summit Racing—from the Moroso 7-quart oil pan to the K&N air filter.
