all that low end power would be nice with a stroker, I just hope I would not have to swap out all the parts I already have for bigger ones like the headers, heads, Intake injectors. All that stuff adds up but if I can use all my 346 stuff and still have something respectable that would be awesome.

I AGREE 10000%!!!! IF you got the cash to afford it always go with the biggest cubes you can and the most power you can get out of any given set-up!!!!

If you stay with a stock bore 382, your heads should work fine if you don't want to buy another set.

depends on what you want to do. at the last shootout, I found myself wanting a 346 cause the class was so competitive. If you are into things like that, I'd say go with a forged 346.

but you can definately use your current headers, heads but may need to upgrade your injectors to #30's with a 383.

Do you plan on racing at any events where engine size will put your vehicle in a specific class? If not, I'd go with a stroker all the way, especially if you are staying all-motor.

If you plan on building a power adder engine, I'd go with a forged 346ci setup. You can always boost it up or jet it up to make up for any lack of engine size.

The best all-around street/track engine I've ever owned was my all-bore 382ci. It made plenty of "usable" power, especially when launching on radial tires. I could floor it at the top of 2nd gear and start to grab. With the 434ci setup, I couldn't floor the car on the street until the top of 3rd gear, and its DAMN hard to keep that patience when you are racing someone. On the freeway, the 434ci was an ***-kicker, but I never lost with the 382ci either.

Just depends on what your purposes are really. I plan to put a stroker in my convertible because its heavy and needs alot more torque, and I don't plan on ever class racing it. The '88 Formula I just bought will be my next trailer queen drag car, and it will be a forged 348ci LS6, with alot of nitrous, spool, 9" rear, etc...

Mike if your gonna spend the $$ for a all forged bottom end then I'd opt for a 383CI shortblock.Your heads are more than adequate to use on this type of setup since the bore to comb. chamber isnt affected as much as a superstroker.

U can run 11.1CR or more and go bigger on the cam w/o sacrificing drivability,plus you'll have ALOT more TQ down low.

If I had the $$ I'd build a 383,The only way I'd go 427 is a Darton setup but there to much money...

Good luck...

with all these comments Im leaning toward the stroker, I'll probably do that ,Thanks guys

Not true, I'm running faster than most of the big boys! Look at Harlan's car, he is soon to be the fastest car on the board! Power added of course...

Also, look at the Cartek 346ci bone stock bottom end cars with heads/cam running mid 10's at 130+ mph, naturally aspirated!

I say 346ci all the way!

I was talking about locally.. Mike has no plans on a power adder.

I just went forged 346 and would point out that there aren't really all that many 383 strokers going much fatser if any. Packages exist for this displacement into the mid tens. Most 422's with a big NOS shot are at the very high 9's. Is is worth it for your dollor? If I were going to put up more money it would be for a 383 all bore first before I went stroker. Hell, for the same money go with a solid roller 346 all forged and you're still getting 500rwhp with the ability to rev the crap out of it.

Ok.. 348ci Forged setup against a 383ci Stroker. On the street side by side. Same raceweight, same gears, and same driver skills. Do I need to say more?

BIG thats not a fair comparo..
Have Cartek build a 383 S2X REVIII setup and see what someone like Brent would run.There is NO way it wouldnt be quicker/faster.

But your car does flatout fly for a teeny tiny 346

I say majority of the advertised 346 running super numbers are lightweights, just my opinion. I plan on a forged 382, plus power adder for an ultimate kill. Problem lies in the suspension, it will take a little more than a Hi-Po 346 to get it to hook any. Stroker, lower revving also, should help save the internals a little more.

That's the point right there No doubt 346's are very good,but line it up with a properly setup stroker and do a roll on at 40mph in 4th and the stroker will kill the 346 in torque..That makes a stroker a powerful street car.On the track it seems like most of the racers are ringing out 346's and going good,but I'm sure next year you'll be seeing more stoker motors running impressive #'s since the Eagle crank has made stroking affordable..(no pun intended )

Forged internals only cost ~ 2000 installed....and Nitrous is > $3/lb.
Most of the cranks available cost that by themselves....
How much are the eagle cranks??? They have been out for only ~ a month now.....

Mike K.

The eagle cranks are anywhere from 900 to 1000 roughly so It really would not be that much more to stroke it, The main thing I have a concern with is the heads but since I should be able to use them I may go ahead and try the stroker route out. It would be nice to have the extra torque but not being able to rev to 7k I think I will miss. How high do you guys think a stroker will be able to rev on a normal basis in order to keep some longevity to the motor?

That depends on the cam Mike..

You can rev out a Stroker to 7000rpm.Just make sure when it's built that there is extra attention put into balancing the whole setup including balancer and clutch assembly.You will also need a big cam to make the power up top too.
