Coming back with a build! Need advice!

Hey guys! I'm back as I realized I need to get my *** in gear if I'm to make Mopars in the Park in June.. need to build a motor.. Here's what I got and what I'm hoping to make, with what I have to spend..


68 383 block - needs full machining but is still STD bore
Stock forged 440 crank - needs machining
440 Source Stealths that need full porting/machining/new springs
TTi 2" under car headers w/ full 3" exhaust
Hughes 3500 stall
stock 727
B body 8 3/4 w/ 3.23's
The car is a stock chassis 71 Demon, with full drag suspension (bolt on = QA1 front, S/S springs/shocks/ B body disc/drums)

Want to make 550-600 crank hp on pump 91

Have $4,000 to spend maybe a little more.. I am going to try for a personal loan here but if not it will be pretty much liquidating my other hobby stuff (RC's, slot car's) to get this done.

I plan on going with Jake at Sampson Racing Engines in Lakeland MN as he is a mopar guy, and I don't really trust the shops around my area (there are 2 within 30 minutes), planning to drop the block/heads off with him and some cash down this coming Saturday but wondering what you guys can come up with - my default plan was always a 438 stoker and has to be NA as I don't think I have enough time or money to go low compression and turbo it..
