Stroker Info / Testimonials

[Route666]

I hope some of you guys can help me with this. I'm looking for information on smallblock (302 and 351) strokers. I was initially just interested in fuel mileage, though I would like to hear about reliability etc.

Details I would like included are:

stroker type (331, 408, etc)
vehicle weight
manual / auto
rear gears
power output
fuel mileage

A breif description of the vehicle's build intentions would be good too. Like whether you built it for drag racing, reliable daily driving, performance weekender, etc.

Also, if you've had any issues with reliability, chuck those in too. I don't really want heresay about specific stroker kits, just reliability from your engine, although I won't knock discussion on the different kits.

Of course, if you don't know everything, tell me what you can, have a round-about guess at the things you don't know.

I built a 347, it was awesome, but the 331 is a better bet for the street with fuel economy and everyday use. Plus, history has shown the 331 better for piston ring life and oil consumption.
The 331 is a nice one for the street if you don't see any track duty.
I have some experience with a Keith Craft 408 stroker, but it was with a large Procharger, so I'm not sure how it would be without it.

2bav8, how many miles do you have on your 347?

 

[2bav8]

Hard to say exactly how many miles since I don't have a speedo/odometer yet (hey, its only been 11 years).

I'd "guess" around 7,000 miles.

 

[Route666]

Anyone else got a stroker?

 

[washMO66]

stroker type - 347
vehicle weight - 66 Coupe 3000+/-
manual / auto - Auto, built C-4 2500 Stall
rear gears - 3:70
power output - too many changes since dyno (estimate 450HP at the crank)
fuel mileage - Don't care, never really checked, wouldn't want to know

Built the car to handle well, a toy to play with on the weekends, drive to work once a week and drag race about three Nostalgia races per season. The motor has been extremely reliable, can idle in traffic on hot Missouri days, drive to the office and carve corners 60 miles round trip with no problems and throw on the slicks and run in the mid 11's consistantly through exhaust with a low stall and not worry about breaking parts.

Some people have commented and I read in some magizines that my CAM is borderline for the street but for my use it's fine. Does is draw attention at stoplights, yes. Is it too much horsepower for my street tires to ever think about hooking, yes. Would I change anything, probably after I get the drag racing out of my system I will go with a stout 5 speed and maybe go race around some corners.

I have had the motor in for almost two summers and it seems fine. Here is my build. Good luck.

Sal...

What block are you using?

Just wondering what hood and aircleaner you are using? And...how big is the air cleaner?

It's a stock steel hood and the previous owner bolted on a 66 shelby look alike scoop for looks and didn't open up the hood. When I went with the Vic Jr I had to make that scoop functional by cutting a hole in the hood to clear the wing nut on my cleaner. The air cleaner is one of those edelbrock triangle looking ones with I thin a 2" K&N filter.

Like I said the only thing that didn't clear was the wing nut and just a bit of the cleaner.

PS - I also have TCP solid motor mounts if that makes any difference.

 

[allcarfan]

Thanks for the input. I dont know about the solid motor mounts. I have a vic jr style intake and a speed demon im about to put on and I was wonder if a 2 3/8" thick air cleaner was going to fit under a hood with a shelby scoop...with a BIG HOLE. Im going to use some clay first to double check.

Sorry for the thread hijack Route666.

I am building a 331 stroker though. TW heads that flow over 300cfm, xe282 HR cam, vic jr intake, 650 speed demon, ross pistons, h beam eagle rods, ...and some other goodies. Hoping for 400 hp to the wheels through a C4 and a 9"

Sal...

What block are you using?

I'm living on the edge with a stock block.

I didn't buy each component of the block at a time.

If it were up to me and had I paid anything close to full price for everything I would have gotten I beam rods and possibly a cast crank because we all know that the block will break at the same level these do so no point on having them stronger with a weak block.

Let's just say I have about 2k into the COMPLETE forged motor.

 

[allcarfan]

Sal....lemme know how long that thing holds up on the 250 shot. I was thinking of running 100 on mine.

If the motor is built well, it will hold up. I had a 624rwhp twin turbo motor on a stock block

 

[Fostang]

Sure thing Shane.

I'm thinking it'll last a long time as long as I keep the 100 octane in the tank.

A friend of mine is running a stock rebuilt bottom with rpm package and 250 direct port also. No problems yet and he's using 91 octane.

Another local guy has a 331 with forged pistons and 250 shot runs 10's in a vert fox with 91 100 mix.

338.9 rwhp, 335.5 rwtq [with out of the box carb, out of the box TF TW heads, and a wuss of a cam (.493 .510) - there's more in it, just don't have enough tire to use it]
Never even thought to check mileage

I've got over 20k miles (most of them hard) on this motor with no issues at all. No oil consumption, abnormal wear, etc.

 

[Route666]

Nice combos guys! Thanks for your input. If anyone else has more, I welcome their input.

allcarfan: since you gave the thread back in an undamaged condition, I'll forgive you... this time *insert shaking fist* lol

Let me guess Elgin cam? From probe industries? CHP etc...?
