Hey guys, bear with me as I think alot of you guys may question what I'm thinking, but here it goes.
Car: 1970 Mercury Montego Approx 3500 lbs.
Trans: C6 rebuilt with shift kit, stock converter (small pilot)
Rear: 2.50 9"
The car currently has a tired D0 blocked 429 with rebuilt D0VE heads (standard sized valves/no porting, but less than 10k miles on them). 1 7/8" headers, Stealth, Holley 770.
Now, for my desired build...
5xx stroker (to replace tired 429 SB) small overbore (prob .030 over) with 4.5" crank. H beam rods (for upgrade later)
Here's where things start to get weird...
I want to reuse pretty much everything from my current combo due to being um....not rich. This means Stock D0VE heads, Stealth, 770cfm carb, 1 7/8" headers, and ...really weird... Stock 1970 positive stop rockers/valvetrain.
Custom cam from RHP with ~220-230* @ .050 intake, ~230-240* @ .050 exhaust and ~.510" lift intake/exhaust so as to work with stock valvetrain.
My priorities are basically to spend the bucks on the shortblock now, and then run it for 10-20k miles in this form, and add aluminum heads/bigger cam/ etc. etc. later. 2.50 gears must stay, carb, intake, stock converter (may have to find a larger pilot one to work with stroker crank) etc. must stay due to budget/driveability concearns. I'm thinking 5k RPM MAX, due to cam size/valvetrain.
anyways, I'm looking for input on what kinda power it'll make (I'm thinking ~450 hp, 550 lb-ft), how'd you think it'll run (mid to low 12's?)/anything else you would change or would/wouldn't do. I'd eventually like to make ~650 hp with different heads (prob P51), and bigger cam, so shortblock will be built accordingly.
Thanks!
