stock 5.9 gives big performance surprise

I posted this in the racers forum as well for the guys who may not visit this page very often. so, if you have read it there then I apologize.


short run down. friends son had a duster bracket car with a 7.00 360 in it. he hurt the motor, and they were looking for a stock motor just to keep him racing until they rebuild.

I had a junkyard magnum from a 94 truck with 121,000 miles on it. told him I would lone it to him until they got the other engine rebuilt. never heard it run but it was supposed to be a good running engine.

he took it home and looked at the bearings. he said they looked great and the cylinders were not worn. the engine was very clean with no sludge. he put a melling timing chain and oil pump in it for insurance.

now, the only mods he did was ordered this intake http://assaultracing.com/?wpsc-produ...ntake-manifold


and put his headers on it from the old engine. used a holley carb, and I didn't ask what size.

just intake, headers, and carb. everything else was bone stock. he used a stock stall converter not a hi performance deal.

car went low 8.20's in the eigth mile with the secondaries on the carb unhooked. it would stumble in the pits if he stopmed it to make the seconderies open. with little time to work on it before practice, his dad just unhooked them and run it on the 2 barrell.

I think the car has a 4.30 gear in it, but it still has the back seat plus a cage in it.

I thought that was pretty damn good for a stock production truck motor. it even picked up the left front tire about 2 inches. it would leave hard as hell for the first 15 feet then nose over and start climbing in speed little by little. thats that low rpm torque cam that was meant for the trucks I guess.

they plan to put their e85 carb on it and go to test and tune this thursday. a high 7 second pass would not surprise me by doing that.
thought you guys may find that interesting.

that intake is a very nice looking piece. it had the dual pattern for magnum or la heads. anybody ever had one of those before. $160 is pretty cheap, but the quality looked good.
