Re: Strokers (kewlbrz)
I agree with you Kewlbrewz about the bore. You always want the biggest bore you can get whether it's stoked or not. I don't think many will disagree with that statement. :flag

Re: Strokers (RACER7088)
Just for some added information, on our G-7. We used a 4.000" stroke x 4.080 bore, for a 418 ci . We produced 512rwhp and 497 rwtq. Our heads flowed 330cfm @ .600 and our cam has .612 lift. We use a split duration cam to help the exhaust. We used the stock block, sleeved to accept the 4.080 bore.
--Peak RWHP 512.0 @ 6300 rpm, Peak Torque 497 @ 4500 rpm
It has over 450 rw torque from 3500 rpm to 5900 rpm.
All tests were done on a Dynojet chassis dyno.
I drive this car daily, and after feeling the torque of the 418ci I would have a problem going back to the smaller displacement for a "Hot Rod".

Re: Strokers (LG Motorsports)
This has been an interesting topic that has dragged out many good points to the ideas of larger motors. I guess if money is no object the big boy motor would be the best option. I agree with all sides of the story. Everyone has good opinions. In my situation I don't want to dump a crazy amount of money into my head/cam car but need another project to make some more power. The 422+ motors are quite expensive vs. a possible "stroker" or an "all bore" combination. I guess this post should have asked the question; " if I was to build a larger displacement motor would I be better off boring or stroking". (Obviously keeping the stroked and bore motor out of the equation)

9D9LS1,
Then I agree with Dennis in his first post that the bore motor will make the most power as long as you have heads to match it. The 422 will have only marginally if any more if everything else is the same but it will be even nicer with more low end grunt. But again as 2FST4U said you could have bigger heads and cam and have more everywhere with the bored and stroked engine! :cheers:

HPGURU, thanks for the insight. I think I will now lean more towards the stroker in the spring if all goes as planned. Still undecided about this upgrade, but if I do it will most likely be a stroker.

Re: Strokers (HP-GURU)
Yes after LG's post the stroker and big bore sounded very nice. Greater than 450rwtq from 3500 to 5800 is pretty incredible.
Nineballs doesn't hit the 450rwtq on the dyno shown, but it should.
Built like some of these 346 putting down 400-410rwtq, the 388 should get around 450-460rwtq. Still very respectable.
Price/performance its hard to beat the 388 all bore tho.
