swaping a 351c for a efi 302 question

[etnovass]

i just bought a 74 eb with a 351 c in it with a c4 and dana 20. i spend most of my time at angles well i did with my jeep and i dont think im going to be happy with the carbed 351c so i just bought a 93 mustang that im pulling the motor out of to put in the bronco. my question is how much work is it to go back to a 302. will the c4 bolt up to the 93 302 any major problems instaling a 93 efi motor. i know that there is alot of posts on efi but i could not find one going back to a 302. any info would be great

Why not just pull the parts and make that 351 fuel injected??? Do a search there is lots of stuff on 351's

It takes a lot of work to inject a C. You don't find a bolt in manifold very easily or affordably.

It shouldn't be hard as all to pull the C and drop in the 5.0. Just follow the standard 5.0 conversion file info. You will need different exhaust as the C won't work on a 5.0. I doubt anything special was done to the chassis when the C was first installed. The engine to trans is teh same on the C as the 5.0
You will have to look at what comes out in order to see what the bolt circle of the torque convertor is. Even though the C has the same bolt pattern as the 5.0 the balance is the same as the early 302.

I can take the C off your hands if you like.

Also there are intake plates that let you put a 302 intake on a C motor. So you can swap the 302 manifold and injection system directly to the C.

is the stock 93 5.0 stuff big enough to run on a 351c. who makes the plates?that sounds worth looking into. i like the power the c has i just dont like the stalling out. will the fi give me a better low end. thank s for the info. is there any body on this site that has done the 5.0 fi on the 351c

Bax, you need to get a commission on the number of people you retain or enlist.

Price Motor-sports has the adapters. That will be $3.00 dollars

 

[etnovass]

$3.00 sonds like a good deal for that info. will it support the 351

Stock 5.0 can just handle a stock 351W. With the extra breathing of the C, I think you will need more injectore and more MAF, then program the ECM to match it all.

Price motorsports make the adaptor plates. Big block distributor fits a C, so a cource of an EFI distributor for the C. Can be done, but expect it to need some tuning to get it right. As for more low end, depends on how much of the lack of low end is due to the cam. While entertaining this, the stock 5.0 intake will choke the top end. But you should be able to run an Explorer intake for enough flow.

So you need the basic '93 EFI system
Larger MAF that won't max out.
Explorer intake to breath
big block distributor, and injectors.
Intake adaptor
Almost forgot, the intake adaptor probably will not let the distributor clear, so you will probably need a distributor riser as well, check that over while shopping for the intake adaptor.

That should get you started on putting EFI on the C. Yes, doable. Lots more expensive then putting it on the W.

The Cleveland was never known for low end torque, all high end hosepower.

Good info on the adapter plates, thanks Bax. I might just keep the 400 in my BB now that I know I can inject it.

Distributor= 351 W TFI change the gear to the big block gear and your good to go. No riser needed for the distributor to fit.

Yes there is an adaptor for the 351 W intake as well. Even the use of the 4v cleveland head is supported. So that is cleveland block, 2v or 4v cleveland heads, 302 or 351 injection systems.

 

[etnovass]

great info guys. now i have to find a place for the 302 to go. will i have to get the 351c dyno tuned to run good

Never known to those who don't know.

If you want to inject the Cleveland, then I'd go the route of the howell or turbo city throttle body setups. Price them out, then price out what it will take to put in your new motor. I think the price will be about the same, and much less work.

how about propane? anybody running it on a 351c

I am in the process of building and injecting my 408C I have 30lb injectors, Roush fuel rails, Trick Flow intake with a 1 inch spacer, 76MM BBK Thottle body, C&L 77MM MAF and Cold air intake. I am running 2v aussie heads and most important, Chuck's (BC Broncos) 24 gallon tank... I need to get a 460 EFI distributor, which will drop right in the cleveland. I have the stock EFI harness and will use a A9L computer. I will have the computer remapped for the difference in cubic size later.

A friend of mine's husband did this to his pantera with stock 19lb injectors and used 5.0 and 351w parts. He used a 351w intake and had the bottom milled to mate with the top of the 'c' block. I will use the spacers mentioned above and make sure its port matched. I like the air gap too There is no water in a cleveland intake.

Like I said before, A 351W TFI dist will work if you change the gear. The 460 TFI is hard to find.
