Default H/C or 382 All Bore/Stroker

I originally wanted to go with a H/C package: S2 Heads, 230/224. With that cam I would want to rev at 6800 or so and would feel a whole lot more comfortable with at least Rod Bolts. But if I tear down the engine just for rod bolts then I know I will end up going with Forged Pistons and Rods for another $1300 or so. I figure I will get 450/420 with this package and all bolt-on's but it will cost me almost as much as a 382 stroker or all-bore that I could get from JPR with ALL forged internals. I doubt a 382 with stock H/C would make as much power as a S2 H/C 346 but the engine would be practically bulletproof for anything else.. turbo, supercharger.. and I still have the option to do heads and cam the following year for even more power when I would have more $$$ (I'm sure that eventually the H/C will feel slow.) So I have a few questions:
-What is the difference between an all-bore and a Stroker engine? Power/reliability differences?
-How much power will I make with either the stroker or all-bore with stock heads and cam?
-Same question with S2 heads and cam?
I just want a reliable set-up that is going to make some serious power. I figure it's best to start with the bottom-end and work my way up and if I'm going to forge out the 346 I might as well go with a bigger engine while I'm at it right?Thanks for any help or ideas.

I was in your exact situation not very long ago. Best thing I can tell you is decide how much you want to spend subtract $500-$1000 and then see what setup you can afford. The money subtracted goes for tuning, injectors stuff that you don't really think of when buying/building an engine. For any of those setups you will need a good set of heads and a cam for good power. You could do a good set of stage 2 or 2X heads/cam and then next year stroke it. I wouldn't spend the money on stroking or boring with the stock heads/cam though. By the way I decided to go ***** to the wall and get a 422 and be done with it all at once.

I can understand if the money is tight that would be a problem but I think that it may be benificial.

Where I am from it is the popular thing that what one guy gets the next 30 get with in 2 months. Going 422 may prevent this if there is the same problem there.

I agree with you there. Look at how many more people have bores or strokers compared to this time last year. Next year at this time there will be alot more 422's but at least I beat alot of them too the punch. A 422 is a **** load of money at one time but I'd rather do that then keep upgrading stuff and losing money every time I upgrade.

How much power are we looking at with the 382? The 422? Only problem with getting S2 H/C now is that I would need S3 heads for the 382 and I would be able to go with a much bigger cam if I had pistons with vavle reliefs. So in that aspect I would be losing money when upgrading to the 382 as well. SO HOW MUCH POWER ARE WE LOOKING AT HERE???

With a kick azz heads cam package you are looking at about 430rwhp on a M6, with a kick azz 422 stroker you are looking at 500+rwhp and torque, but the numbers under the peak numbers (where drag races are really won) would dominate over the heads/cam, especially in the torque dept. Ultimate 1/4 ets are determined by the dyno numbers under the peak number and this is where the stroker would really rock, as well on the street and track. Not postive on the 383, but educated guess would be between 450 and 470rwhp with the best components.

I am in the same boat as you and have decided to just get it over with and do my MTI 427 ironblock stroker now instead of non stop upgrading, etc.

Do the stroker 422 if you can afford it and you would be done once and for all! <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" /> The way i look at it, its a huge investment and outlay of $ now, but one that will ultimately save me $ as my nonstop ugrading is a big waste of money and energy!

IMO

Figure out how much you are willing to spend first. I think $10,000 for a heads and cam car w/12-bolt is a good starting point. $20,000 for a big 422/434 & 12 bolt isn't too far out. A stroker or big bore should be in between w/12 bolt. If you do the work yourself you can get by on a little less cash.

With the power levels your talking about a 12-bolt would be a good idea ~$2300

A new drive shaft, rear sway bar, etc could add ~$500 to that.

Heads for a Big Bore require more work and usually cost more than the typical Stage 2 head. Say at least $2300 maybe $3500. LS6 heads are nice as extra cubes can really use the LS6 head.

Rotating assembley for the stroker or for a 7 liter + will cost ~$2000

Rod's & pistons will cost ~$1200 to $1500

Tuning plus supporting bolt on's like headers and pulley's, LS6 intake or port matched Holley intake could easily eat up another $2000

If the car is an A4 plan on a new tranny as well.

If the car is a M6 plan on a new clutch.

Might be more fun to have a nice H & C car w/12-bolt and a little extra $$$ for stuff than stroker/big bore etc and be tighter on cash.
