Q: I have a 1973 454 big block Chevy. It has a 8.5:1 compression, stock oval port cylinder heads, a Crane PowerMax camshaft, and Edelbrock Performer intake, and a Holley 750 cfm carburetor. The engine needs an overhaul but I would like to retain the stock cylinder heads and intake. What would I need to
Q: I want to get 450-500 horsepower out of my 2002 Chevy Camaro Z28. My car already has an 80mm BBK throttle body, a Granatelli mass airflow sensor, an SLP LS1 airbox with K&N filter, and a Flowmaster American Thunder exhaust system. I’ve thought about installing a new camshaft, cylinder heads, intake manifold, and a
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
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
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
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
Q: The culprit is a 1989 GMC 1500 4×4 with a 350, automatic with overdrive, a 3.42 axle, and over 150,000 miles. It has recently developed a powerful thirst for Texas tea, consuming 1 quart every 100 miles. A new PCV valve didn’t fix it, and a valve job only eliminated the smoke at startup.
Q: I have a 1986 Chevy Camaro RS. I’d like to build a 350 for it that puts 400 horses on the ground, and I’d like for it to be an “all-motor” Camaro, without nitrous. My plan includes some high-compression pistons and a big cam. I was also thinking about putting 305 heads on the
Q: I’m getting ready to build a 406 small-block to put into my Camaro. My question is about the use of block filler. I’ve read that if you fill the block to the bottom of the freeze plug openings, that it will increase the cooling ability because this limits water flow to the oil pan
