well i look it over i think it may not make 420hp .but should be 370 or so i could tell you abit of pull a rabbit out of my hat B.S on dyno numbers .till it running on the real dyno . cam is small but your low on cr and thats ok. if that all you have. with out doing some decking and getting the piston were it needs to be and a 4 angle valve job and some tricks i know . i will stick at mild to hi 300 hp. 650 cfm is abit small but off idle response should be good TQ numbers everyone over looks but thats what you really need and you should have lots of that.rv15h ERSON 214/214 ..492/492.112 ADV 4 put the intake at 108 thats what my book list it at

Thanks for the info pat!

Oh and I forgot to add, the heads will have a fresh 3 angle valve job.

I hope the truck proves to be a good sleeper that I can go cruise the line with and have some fun in. There's a guy that cruises the line in an 86 chevy shortwide with a mildly built 383 in it with vortec heads and a nice sounding cam. I hope to give him a good run from a roll!

yep with a good tune it will not be hard to blow the back tires off .i say that any good machine shop the standard valve job is 3 angles. i use more at times or a full radius cutter with a 45 on the EX and back angle the ex valve and other things

Thanks Pat
