Stock block 302’s will live longer with over 500whp with a turbo set up! Unlike a supercharger set up. Supercharger set ups pull on the crank causing vibrations all day long making easier for the blocks to crack…seen and read about a couple turbo set ups living at 700whp reliably on stock block 302’s
Badass! I ran a stock block well north of 500 wheel for many years on a stock block with girdle, pony down turbo setup. Never blew. Car has a dart block now. There’s not much to those two bolt blocks, but can hold some power.
Nice combo..have a TTrim on my stock block with a stud girdle, track heat heads, stock rods, pistons, and cam making almost 500 to the wheels on 10lbs of boost. 10lbs with 4" discharge into 70 to 90mm accufab race throttlebody on pump gas. One day ill convert to e85 or race gas and see what it will do, but its been a 13yr reliable combo, so don't want to kill it, but will probably sell it, and start new with a notch and dart block, etc...
I personally have built a couple handfulls of late model 302s that are still living on 1k turbo and supercharged its alot of work poor the block halfway and cut the mains for a 4 bolt main even though the cap webbing in block dont have much its the caps bouncing that kills them i have never seen a 302 that is cracked without very bad galling under 234 mains wit 2 bolt i have taken apelart multiple builds for refresh on my 4 bolt conversions with no evidence of caps bouncing all it takes is a real tight tune
I’ve been watching a good while now and one thing I know is that you know how to work the bug out and get those turbos to do what they need to do. I meant to stop and talk to you in Darlington the other weekend but it was just too much going on
I have been making 570hp at the flywheel with my stock block 302 for 3 years. It is not filled but I also had it internally balanced when it was built and I dont rev it past 6700. They survive if you aren't a dumbass trying to spin the 50oz weight 7500rpm
Not to be bashing the Ford platform, but I had a 02 Camaro w/a 403" LS2, and it was making 567hp at the tires, more than my dad's solid roller BBC! Just a mild, hydraulic roller nitrous camshaft, decent heads... nothing special, no fill, aluminum block that's 100lbs lighter than its twin iron block! My new turbo setup, which is a iron 408, Dart Pro1 225's, best valve trane you can get, with a FIS 91/102 turbo. Should make some steam for a streetcar with a/c still! I was steered away from doing a half fill, so I could get more strength, but still run water through the block... 570 is nothing to be ashamed of though, what's the car run..? My 02 went 10.30's on motor, 8.50's on a non-progressed 200 shot! It still made flatline power at 7500rpm, which is where we stopped w/stock lifters! I'm sure your car is about 7-800lbs lighter too!lol
25 psi of boost is as you know 2.72 MAP. 715 whp / 2.72 MAP = 263 whp from the theoretical NA engine. This is so low I suspect something must be wrong somewhere as the Edelbrock Performer RPM kit is advertised as 367 hp. :)

Ford designed the low deck Windsor to be light enough for a Falcon and began at 221 cid (the tall deck had more beef). which is why many 289/302's don't want to bore over more than .040 inches. but some "casting mistake" blocks will go .060 over. also, the original firing order set the front cylinders off at the same time, so if you use an older grind of camshaft, plus the different crankshaft weight found in the fuel injected Fox 302's, and then crank down a blower belt on that front crank snout...
Boost is just a measure of restriction, that turbo is barely into its efficiency zone if I had to guess and the motor just cant move the air. The pulls are also shortened, which I'm sure with more RPM it would pick up power.
lmao apples and oranges comparing a sbf 302 to a LS 5.3, pull that 5.3 and put in a 305 sbc and see if you'd like what that 305 does with 22psi and a VS 80. 🤣
Wrong. You can run 800 plus hp on an old school block. Harmonics are the issue with the blocks splitting. Balance and the right girdle will solve that issue. David Vizard has proven this myth wrong numerous times. So quit being apart of the lies and spreading false information.
Well me being FORD TO THE CORE stock block is two bolt mains so he's a TRULY STOCK BLOCK 302 lol the SVO blocks are also considered stock block and the center 3 main caps are four bolt mains and they'll hold a bit more.

The Roller block is one that's known for splitting older ones are OK mexican 302 mostly came in trucks production 69 to 75 most more common in 71 to 74 I think... ours came out of a 72 f100 ranger
Lets clarify, a 302 is not something that came in fox bodys. Its the 5.0 ho rollor blocks that are weak, and the old 302 blocks are quite strong, mexican 302 blocks are even stronger. And inb4 the (but a 5.0 ho is a 302) yes.. in Displacement only the blocks are different.
The 302 was available in EVERY year of the Fox Body Mustang from 79-93. They were 2bbl carb engines until 83 which was the first year for a Holley 4bbl, but they always had 302's.

Last one was 615 i think, RPM heads do not flow all that good (if stock ports) so at the wheels its not that bad but it will make more loaded longer like on the track
Dyno numbers don't matter. It made over 700 rwhp later in video. It traps alot of mph and likely makes alot more power this is why dyno numbers don't matter.
@Jojo-ix8tg dyno numbers don't matter and how should it be 1000 easy? Because coyotes do that with modern tech and dohc and alot more rpm? It traps at the track as if it makes far more that is what matters not dyno numbers.

I wonder if the block is filled all the way with concrete because he said they don't run water through the block only through the heads
Dont know who recommended that turbo or if he already had it, but that is way to large for his combination.
Especially the hot side..
im messing with a sbf also, i have watch those videos of joey with the nitrous combo i few times.... taking notes.

Yes, it runs a coil near plug set up. Similar to an LS. The Holley EFI controls the coils.
I presume the block has been filled for strengthening?
Sick car brother. I like it a lot.
Broke my stock block at 365 hp with a straight drive.
