Has anybody played around with the idea of using a Ford V8 instead of the Chevy V8? The Ford is a much more modern engine with DOHC, 4 valves per cylinder and it can certainly cope with more revs like redlining at 7'500rpm and peaks at 8'000rpm.

I'm not sure that dohc is 'modern'. In many ways it's a pain.

First of all the 4 cam ford Coyote motor is wider than the ls motor by a bit and where are you going to put the headers, The coyote is heavier by 15 to 20 lbs but more importantly the weight is up high in the car. The crate ford Coyote is $6800 makes 412 hp at 6500 rpm and 390 ft lbs at 6800. An LS 3 from Summit is $6800 and it makes 480 hp at 5900 rpm and 465 ft lb at 4600 rpm. Now here comes the kicker, anyone who is not a dyed in the wool Ford or Chrysler fan here in the states will tell you that the cheapest horsepower to be had has always been the SBC and now the L.S. is right on its tail. No argument that you can make silly horseppower with either the new Chrysler Hemi or Ford Coyote motors but I will guess that you are going to pay 30 to 40 % more for the same parts. Just think what a simple cam change would be in dollars for the 4 cam FORD vs the LS motor. Lee

But the fun of driving a engine that likes high revs is so much fun. The sound the Coyote makes is very intoxicating. It is a modern engine and is priced well. I'm not a Ford lover but these are great engines.

My build is old school 327 with Italian help.

This should be a good topic. where is the pop corn ?

I have been researching GT40 stuff for some reason.

there are a couple of different mod motors, bell housing is the same from what i have read, deck heights and firring orders are different. a 4 valve motor will allow more valve curtain area for less lift than an equivalent 2 valve head. not talking about the valve size here, more about the area around the outside of the projected cylinder that is formed between the valve head and the top of the chamber. end result is that you don't need big expensive lightweight valves as they do not need to lift as high off the seat to develop the same cylinder flows. this allows for a cheaper valve train at the cost of more cam shafts....so no difference really.

cad model of the Coyote.
http://www.gt40s.com/forum/gt40-tech-engines-induc...

this has a good right up on the Coyote engine. Valve lift on the BOSS 5.0 Coyote is already at 12mm or something, which is a good amount for a 4 valve head.

you really should be comparing the Coyote with the new LT1 direct injection version of the LS engine.

Cams, intake, exhaust and tune which is what you would have to do for an ultima, well maybe not the cams, and that gives you a 8200 rpm red line and 620hp i think the article said that was on a stock un-opened motor. certainly looks and sounds smoth in comparison to an LS.

As nice as that video sounds it doesn't do it justice, my neighbor has one in a cobra and my spine tingles every time he drives by. It sounds like Maserati VB with more grunt.

This is getting close to completion and is local to me, should be nice to hear it run.

he has had a few issues with the RCR body if the build log on GT40s is anything to go by. Some of which were issues created with the addition of the rear gulf guards, whilst I think some may have been inherent with the RCR body.

Hopefully I get a chance to see it running at some point.

nice build.
I really like the alloy chassis on those, at some point I feel I must "tick" the GT40 box as it were.

im undecided about the RCR40. this is the build thread on gt40s.
http://www.gt40s.com/forum/gt40-build-logs/26333-j...

after seeing what had to be done to get it to sit symmetrically, almost every RCR i look at now looks off.
RCRs marketing is very well done though.

I wonder if Ford will ever produce a crate engine version of the new (announced today) Mustang GT350. Flat plane, naturally aspirated, revs to at least 8K (I believe, though its not yet confirmed). And does the new motor have the same dimensions as the Coyote?

If a crate engine is not in the books, at least the sound of the exhaust is already available...
