So, I am looking at upgrading my 1995 mustang gt's 302 engine but the stock block, as you all know, isn't the strongest. So, I was wondering, is the Ford Performance M-6010-BOSS302 block compatible with oem parts, and if so how much and what exactly will I need verses what I can keep stock, until I can put more new parts in.
Is the BOSS 302 block oem compatible with the 95 302?

Yes but...
Why?
What I mean is: How much power do you want in a street driven, 3400 lb car? What are you willing to spend to make that happen?

I was thinking around 700hp max depending, but prolly chill at 400 in most applications. The reason being is, 1. I was wanting to slowly build up overtime starting with the block 2. oe parts are alot easier and cheaper to find if something breaks I can install the original part from my current and lower tune down till I get a replacement, and 3. Just cuz the block can handle up 500 hp doesn't mean it won't bust at 400 since it is closer to the top end of its rigidity and I would prefer a bigger cushion on how much the engine can take.Yes but...

Is it fully oem compatible, or what would be different?

Here is what a 700 HP build looks like:
Mine:
Dart IE Block
.030" overbore, 3.250" Bryant Crank (331 c.i.) CP Custom Pistons (8.5:1)
AFR 205 heads
TFS-R w/ Box upper intake
75mm Throttle Body (a mistake due to the HP kit's outlet size)
Cam: HR 228/[email protected], 114LSA, .604/.573" lift
Probe Shaft-mount 1.6 roller rockers
GT4276R with intercooler using an HP kit with 3.5" downpipe and 3" duals through Ultraflows and dumped
Baseline: 362rwhp & 329 lb-ft (very lean and breathing through turbo exhaust piping)
15psi: 763rwhp & 687 lb-ft

Yeah, and this will mostly be 400 hp with occasional tune up to 600 maybe 700, as I do plan to reinstall the stock exhaust system for street applications as so it will pass smog.Here is what a 700 HP build looks like:

It's compatible. You are making the right choice. The reputable engine builders won't even rebuilt a stock block anymore. The factory pushrod blocks have been out of production for over 20 years, and what you find at the junk yard is in fact junk now. Woody at FordStrokers has only offered fresh block engines for over a decade now because over half the production blocks he brought in for overhaul had cracks in them.

There is nothing making 700hp that you can easily swap a stock exhaust back onto. I'll sell you my catted frackenpipe that I used for 15 years to pass emissions here in Georgia. I've been emissions exempt here for a few years due to vehicle age. The frackenpipe has a flex H to fit all brands of long tube headers, and looks like it was welded by a toddler, but the car passed emissions with flying colors.
