Donnie, stick a terminator motor in it with a twinscrew on e85. 750rw all day easily. The bonus is Matt willhate it almost as much as he hates being employed. Lol

Lmfao, that cracks me up. But I would like to stay pushrod. I guess I just want to be old school about it.

Yeah Chris is a good example of a local fast SBF, but we both know thats a nice ass motor. But look at how many fast Chevy based motors there are...

I guess I'm still a cheap ass, I also like it when parts are easily available. I break too much and race way too much to deal with SBF's

Donnie isn't a punk ass bitch to do something like that.

I like my new new job, thank you very much.

A pushrod motor will be much cheaper then that and make just as much if not more power depending on how aggressive you get with it.

The 347 in my car now can be duplicated for around 3k with brand new parts, or less then 2k with used parts and you building it and it made 430 to the tires, got 20+ mpg hwy and drove great.

Same thing can be done with an LS motor cheaper, and no SBF I've ever owned got the same mileage as any LS I've owned. Which have been a LOT of both

I will agree the ls gets better mileage, but apples to apples they cost about the same to build with similar hp results. I have built a bunch of both, my ls1 in the truck actually ended up costing more then My 347 in the mustang. I doubt he is much worried about fuel mileage if he wants a big hp car. It's is nice but doesn't always come with the territory. Different strokes man.

A short stoke 347 with the proper cam, heads, intake with a little boost from that monster blower will easily make 600-700 and drive smooth as can be.

I couldn't agree more.

What rods and pistons would you use with a short stroke 347? Would that be a 331 rod with the bigger 363 pistons?

Yes and no. A 347 and 331 both use the same rod but the compression height is different thus different pistons. normally you would use a 3.25 stroke crankshaft, along with a 5.4 rod and a 4.125 bore piston. Personally I would use a 3.25 stroke crankshaft, a sbc 5.7 rod, along with a set of custom built pistons that have the correct xompression height that will put you at a zero deck and 4.125 bore. Reason for the sbc rods, is because they are readily available and having the longer rod gives you a better rod angle thus less side load on the pistons and less pressure and friction on the cylinder walls which could equal a smoother runing engine that will last longer and make more power. but you will need to get a crank that has the rod journal cut to fit the 2.1" sbc rod journal rather then the conventional 2.123 sbf journal. most of the parts will be easy to get ots parts except the pistons. they may need to be custom made but i would have to do the math to figure the compression height needed along with the correct pin size, and ring placement and thickness for the application. I will have to do the math later but it would make a killer combo IMO!!
