what could i do with a magnum 360?

If you're going to run that loose of a converter I would recommend the MP cam from the crate 360/380 horse 501 lift/292 duration and the M1 single plane which would give you almost the identical set up as the 360/380 horse crate engine. If you have power brakes this one is not for you. I have read that these crate engines dyno at almost 400 horsepower. The limiting factor in magnum heads(stock) are a max of 525 lift otherwise the retainer will hit the top of the valve guide. I installed a 496/512 lift cam in mine and only have 20 to 30 thousandths clearance. The other way is to buy Hughes retainers that will allow 125 thousandths extra on the lift. Last time I priced the they were about 65 bucks. The cheapest cam situation I was able to find was a new factory core ground to the specs listed above for 130 bucks to my front door. All the new magnum cams are very pricey. If youre interested drop me a pm and I will give you the guys email.
