500 rwhp 350 chevy in 1986 Monte Carlo

[Bosshog]

So somebody already installed a 350 in your Monte?

yes there was one in there but im probably gonna end up scrapping it and get a block from something else and build it from scratch so I know what im getting into.

For what machine shop costs are these days plus finding a good one you would be better off starting with at the very least a crate short block and build from there.

im wasn't really planning on getting a crate motor. Id rather go part by part.

So what is your budget for the engine to reach your goal of 500 RWHP?

if we are talking just the motor than i was thinking 5-6 grand

Stroker kits $1000 or less, good heads $2000 or less, retro roller cam $500, intake an carb $1000, machine shop???

Or do the popular thing an ls it. Don't get into a rush, watch the classifieds for a 383sbc or bigger, might find a cheap one as the season is just about over.

im definitely gonna stick with a sbc 350 and will end up stroking it to a 383 tbh. a 383 crate motor for 2 grand isnt bad at all. just gotta then figure out what parts work with it. also gotta figure out the correct size cam.

600hp in a street motor on 93 octane.

Scrap your factory block plan. Here's the cheapest route I know of - Dart SHP block 4.125 bore, forget the 383 and jump to a 414-421 3.875 stroke. It will fit with minor clearancing of the oil pan rail. Forged pistons with an 18cc dish - JE preferred. Forged rods, will need the best H Beam you can find or I beams and clearance the cam. Heads - AFR or Profiler with no less than 210CC runner. Solid roller cam with no less than 245/250 intake/exhaust duration. 1 3/4" long tube headers. All of the remaining goodies - $8-10K.

Your budget begs for forced induction. Your current motor with the ring gaps opened up, fresh bearing and oil pump and a 76/65 or 78/75 T4 Chinesium turbo and you'll make 500whp look slow and you'll be on your budget. A FT cam swap to a Comp XE268 will get it done.

REAL 600HP is LOTS on the Street. The SBC in my Malibu I'm guessing (not dynoed) is around 575hp. And it ran 6.65 in the 1/8th this weekend, that's 10.30-40's in the 1/4. All steel but the hood. 3250lbs with the driver.
The motor isn't anything crazy but not really streetable either...383, 200cc cast iron Dart heads, 680 roller cam, 12.5:1 compression, Victor Jr Intake, Rupert 850cfm Alcohol Carb
