how would you build your 347 for a drag only motor

One of my friends came to me and asked what he could but in his 1970 maverick with out cutting up the engine bay he ran a 302 in it this year but the motor wasnt cutting the mustard and he would like to get in the 6's in the 1/8th mile The car weights 2200lb with the driver and has a powerglide with transbrake also is tubbed with a pair of 33x14 slicks and 5.14 gear . So my ? is how would you great people of the forum suggest to build his 347 ????????


all who know come forward please and help

Man. that's one light maverick! Seriously, though, Chilly's on the right track. It will take a lot of cam, lot of compression, and big carb/intake. With a stock maverick front chassis...you're pretty much limited to a 1 5/8 or 1 3/4" header primary size. I'm running the same basic car, a gutted '75 model, ran a 393w all year til it let loose. Best was a 6.58/110 in the 1/8, 1.39 60' (footbrake). Car weighs 2700 lb w/ 160 lb driver. Working on a stock-stroke "W" for this year. I think a 347 would be great for a mav, but you'll have to figure out a way to get all that power to the ground! Luckily, a mav's chassis is pretty solid and the rear suspension works pretty darn nice for a factory setup!

I had a 347 built for my Maverick as follows. I used an Eagle stroker kit, forged steel crank, forged H-beam rods and 13 to 1 SRP pistons. Crower solid lifter cam, .605-.619 lift and 266-276 @ .050. Victor jr. heads out of the box, Victor jr. intake, 930cfm carb, 1 5/8 Hooker super comp headers, 1968 Mexican block with main girdle, MSD billet distributor. Engine was dynoed @ 500hp @ 7000rpm and 430 ft.lbs @ 5250rpm. Car weighs 2820lbs without driver and runs 11.0's @ 121mph @2500 ft. corrected altitude. It has a 5000 stall 8" convertor. I run 28x10.5 ET Drag slicks with Caltracs. Best 60ft is 1.53 with the front wheels up. That ET converts to about 7.2 sec. in 1/8 mile. The only mismatch in setup may be the headers but I haven't found anyone that makes 1 3/4 " headers for a Maverick. Does anyone know of a source? This engine in a 2200lb car should produce about a 6.6sec 1/8 mile. Hopefully this is useful.

With a 302 based engine, you'll need all the gear you can get taking off... which begs the question, "Why doesn't the car have a C4?"

Cubic inches are your friend. If you can run a 351W based engine, things would be a LOT easier. You might even get those #6208 Hooker Super Comp 351W swap headers (for 64-70 mustangs) to work with that maverick. Someone here got them to work in a granada with minimal work.

Good Luck!

Thanks guys this maverick he has is a awesome car just didnt have a strong running motor. Just maybe you guys might know the car it is called cardiac arrest its red and white. MIke he likes his powerglides and cant talk him out of it. Thanks again

nope...6208's wont work in a maverick.
tried it, ruined one side...then broke down and made my own. And that was with chopped towers!
