Magnum 300 crate engine - how should it go when tuned up right?

Also last but not least:

If engine checks fine but you search for more HP -Do NOT and I repeat DO NOT re-create the Magnum 380. The move to that big lazy single plane and that big stupid lazy cam on a truck long block WILL result in less performance. Believe it or not the performance starts in correcting all the shitty machining in the short block--then the Magnum heads can be improved easily or move to EQ's and then a bump in cam and you will pickup about 100 hp. Your carb is not too small, you don't need a different intake etc... J.Rob
