302 with 351 Windsor heads ?

[1989]

Ok so I thought you guys would like to see this lol I'm thinking about giving this guy a call to talk to him about the 302 race block with 351 heads .....

 

[shane96ranger]

What is He calling a race block? Is that what He calls a roller block? And again, the 351 heads really depends on which heads they are.

He's saying its a 302 racing motor with 351 heads

since my engine is on the high-performance side. i run a Holley ecm, which has far more tuneability than any OEM ecm.

Your stuck in the 70's, man. Any OBD2 stock ECU can be tuned easily and far supercede any carb on the market, period. We can argue this point til the end of time, but the fact of the matter is, Ford no longer uses carbs on their motors since 85. There is a reason for that, technology has proved that efi is superior to carb. With either of my explorer motor setups, I can change timing, spark, and fuel curves without popping my hood or grabbing a wrench, in less than 2 minutes. Unless you have an aftermarket ignition system on a carb motor, you can't adjust spark curve. I can adjust any of the three at any rpm. If I want more fuel at a given rpm, say like 15% more fuel between 2500 and 3200 rpm, cause that's where the torque band is, I can do that with efi, you can't with a carb, not without affecting air/fuel ratios for the rest of the rpm band. Don't get me wrong, carbs work for some people, but they are yesterday's technology...

Your stuck in the 70's,

you crack me up

i would say not only are you getting this all wrong, you are stuck in the '90s. i'm not stuck in the '70s dude, i'm with the now

there isn't a single factory OBDII ecm I am aware of that can run 24 injectors. tune itself, run not only ford style IAC, but the GM step-style IAC. it can run not 1, but 2 drive by wire throttle bodies, 12 channel dis output, works with both bosh, and NTK sensors, integrated water/methanol injection controls, integrated data logging. stores 4 different tunes internally, and has individual/independant fuel and spark tables for each cylinder (most OEMOBDII ecms don't have a capacity to do that) I got my ecu used for $300.00 btw (they sell new for $900.00)

you can't adjust spark curve. I can adjust any of the three at any rpm. If I want more fuel at a given rpm, say like 15% more fuel between 2500 and 3200 rpm, cause that's where the torque band is

but I can tell you that since I can also program for each individual cylinder I have control over 4 dimensions at any given RPM, not the "3" that you are touting as "better".

so just like I said, mine has way more tuneability/capability than some OEM OBDII ecm. It would take a mentally disabled person to argue against that.

*edit I read your post again, it seemed like you might have mis-read my post, and somehow thought I was talking about a carburetor? (I did say ECM or ECU though) if you somehow thought I was talking about a carburetor, i'm sorry. I think we are both on the same "EFI is awesome" page. Just with a misunderstanding

that is exactly what happened.

No harm, no foul. And yeah, I was talking about carburetor vs efi, not aftermarket efi vs stock efi...

The Windsor heads interchange, and the dowel pins in a 302 block will hold the 351 head in position just fine without accounting for the larger bolt holes.

on a stock engine sure.

anything abused or hi compression or pushing air will pop gaskets in short order.
