THANK YOU SO MUCH. SOMETHING TO CONSIDER. PERFECT FOR MY DAILY DRIVER.

[heyyou]

I bought the 331 kit from you guys can't wait to throw it in

[damianhughes]

Is the 347 a short lived engine for a weekend cruiser

[mustangguymoreau]

Do you guys think it's a good idea to chamfer the oil holes in the crank?

[DieHolden]

I have a good 78 302 short block.. I'm just thinking.. I'd rather have a 351 but what if?

[winfordt.mcguillacutty]

You said that the 331 was a great choice for naturally aspirated motors. Why not make a forged crank for it too ? If you do I apologize. I just get lost trying to find one online

[JoseMorales-epid]

Anyone got any experience with these kits on a 302 mustang? Curios on what the reviews are from someone that's been running it for a long time

[jacobkelly]

so, i want a 1968 ford mustang, say if it was originally a 302, can i stroke that 302 to a 331 with these parts? in the title of the video and like you said, " for 79 to 95 fords " so could i use the original engine, or use an aftermarket 302 to stroke?

[jody]

So is the 347 oiling problems figured out? Been out of the ford loop for a little bit.. building a 331 or 347 efi ranger on nitrous for an everyday driver and trip truck. all else being equall.. what's the hp difference between the two?

[eduardogonzalez-mktf]

What about that flange that the crankshaft has where the rear main seal goes? Isn’t that a problem for the 87-95 sbf blocks

[CJColvin]

Would this Stroker kit fit on the 92-96 Ford Trucks with a 5.0L (302) Windsor V8.

[jamesfitz]

Are you gonna start offering more parts for 1996 Cobras?

[therealheadscratcher]

Will this kit work for my 86 E150 with the efi 5.0?

[bigchesse]

have any one ever took a speed density motor and stroked it out

[anthonygrau]

Actually you mean 5.0 ford blocks . why you say only mustang I do not know .

[MegaScott]
