428PI vs 390

[Dragon]

How much does he want for the 428. In 1968, 1969 and 1970 Ford made better heads in Canada for 428s than the US did and the racers would sneak them down to use in Pure Stock and Super Stock as an instant power boost.

He's asking $6000.00 with a rebuilt c-6 and new ( edelbrock intake, 750 edelbrock carb, headers, alt. & powersteering pump )

ouch keep the 390 for that price you could have one have hell of a truck.

The 376 Aluminum FE I am designing is 7500 with SFI custom piston, crank, rods, intake and dizzy.

Thats why i was hesitant but things cost more up here.
Parts for the 390 are still going to be a pretty penny.
Sounds like your motor is going to be a sweet deal, still out of price range

[Dragon]

Thanks.

I got a hair up my *** to build something totally different and try some variations. My rod to stroke ratio is way different that is why custom pistons and rods. 2.15 to 1 compared to a regular of a 390 1.716 or a 360 of 1.8686 to 1 My fallback though pricey will still produce the same size engine but with more piston friction. of the 360 rod length.

Dragon, whatcha building? Even with a 3 inch stroke you'd need a 7.5 inch rod for that ratio, and thats a 1.07 CH I suppose you could offset the pin for a little extra rod, but it wont be much

Is there enough deck height on an FE to get to that number?

I originally assumed 4.13 bore / 3.5 stroke, but you couldnt get to the rod ratio you mention. However, that setup with a 6.8 BBC rod would rev pretty well and have a 1.94 RR and a 1.64 CH. That'd haul the mail

I am after a fully computer controlled all Aluminum side oiler 376. 3.3 stroke with 4.31 bore. Low end torque and low friction. I know that the long rod will kill some torque due to slower rod speed, that stuffing the cylinder with the lower high angle rods give during reversal. I am in this design trying to break friction's limit on how much torque I can get by 5000 rpm while getting better mileage. My goal is really 400 plus ft lbs of torque.
If my design fails oh well I will put 427 rods in it with more standard pistons.

Full SFI and if I can get a timing wheel for EDIS that will be my ignition otherwise a TFI mated to a FE shaft and lower housing

Arias and I have consulted on the Piston deck height we decided on a oil control ring below the piston pin (full circle skirt) to keep from pushing the rings so close together there is no safe land area left.

Crower is suppling the rods machined from 6065 Aluminum with them also supplying the crank. I did some work for Crower years ago and we still talk design concepts a lot. The cam is still in discussion we want to try a full roller with roller cam bearings and roller hydraulics. The lobe pattern will be based on the Power Beast FE with some changes.

72cc 170cc 2.09"/1.66" #60069* I wanted the GT exhaust bolts. I am also looking at Dove aluminum heads MEDIUM RISER SK-35369

Edelbrock was supposed to send me the machine specs for a Victor EFI manifold so I can have the Streetmaster I got, machined to the same specs for the injectors. It has been a month so maybe??

That is most of it.

Sounds like a great project, going under the pin with the oil ring should work, although I have never tried it, a full skirt should be strong enough, and as long as there is enough bore at the bottom it should do pretty well.

It'd be nice if you could get the EDIS to work.

I'd have to guess 400 lb ft is pretty conservative, you should be able to do that easy. Cant wait to hear how it works out.

I'd steer clear of the Dove heads though, about every other set seems to leak I have heard. Although I havent used them, for what you want to do the Edels with a little bowl work and a nice valve job should do real well.

Thanks about the Dove heads.
