Default question about vette doctors 550 px

i have a 1998 c5 at the vette doctors for heads and cam. before they start working i was thinking of redoing the bottom end making it a 383 or should i go 402 for about a grand more, also is there anyone out there with a similar setup. what kind of hp did you get.

I just did a 383 with the Vette Doctors. The decision was 347, 383, 402, or more.

The decision came down to the 383 or the 402 for me, I ended up with the 383 so I can retain the LS6.

Good Luck, my vette is going back in today to do the clutch and turn the boost up!!!

Well, that should be one nasty little beast bro!
My 382 stroker (non-bored using stroker crank) made ~490 on a dynojet on heavy azz 19" wheels, 93 octane and on a 90+ degree day w/ no tricks.
With the bore and stroke, you should easily attain your goal, although the real numbers will show at the track. And I'm sure it will. The Docs have made some awesome machines over the years.

Not sure why you'd want to keep the LS6 block, but um, yeah. I like the 383 just cause it's less costly than going up to something that'll need crazily bigger heads and intake.

People always forget to say which DynoJet it was. Different models perform very differently. And you never know what tricks a tuner has done.

Bored and stroked?Dude the 4.00" stroke and a cylinder hone = 3.905 bore which makes it a 383.Why would you think that a hone job that equates to one cubic inch will easily make 500 HP?Obviously the stroke is where the additional big cubes come from.

Dyno number comparsions are tough...all things are not equal...unless your on the same dyno at the same relavent time you can forget drawing a positive conclusion.Take it to the track and your trap speed will give you a relative amount of HP produced on that day.

You also save some weight unless you spring for the aluminum block 402.

Have fun with the new set up.
