427 - Just so you can say you have one under the hood.
I do not believe there is enough meat on these blocks to go that far.

Re: [Poll]: Engine Rebuild Choices (scorp508)
I would for a 383 over a 396 for a couple of reasons.
1) The SR and the heads you have are going to limit how much HP you can make.
2) You don't need any more torque.
3) You do a lot of driving and a 383 has a better rod stroke ratio and will last longer. (a 6" rod 355 will last longer than a 383 also.)
4) Cost, a Forged 383 kit (with a forged Scat Crank) is $1400, an all forged 396 kit is going run $2600+ (with the same exact rods/pistons). The more expesive crank are a better brand and quality, but even a Scat forged crank will be able to handle a 383 SR with a decent 150 shot N2O. BTW May there are cheaper 396 kits, but I haven't seen any. (I haven't look that hard though either)

The engine in the car is going forward as planned whenever I get off my butt. This new one is going to be something else. I am not sure what. Maybe I will just rebuild it to a 355 L98 completely stock as a backup. I do not know.
Although the idea of taking my time and accumulting the parts for a low compression 383 or 396 and dropping a supercharger on do sound tempting. :)

Re: (scorp508)
If you do a supercharger then I would stick with a 383 for ring stack height consideration. Otherwise go for as many cubes as you can get. Even with the same intake, etc. Even if the 396 was so choked by the intake that it didn't make *any* more power (which I don't think is too likely) it will make the same power at a lower rpm - have a flatter torque curve, etc.
If you go with forged parts, quality 383 stuff costs the same as 396 stuff - the only real price break comes from using a cast crank (which is perfectly fine) - though that limits you to a 383.

Re: [Poll]: Engine Rebuild Choices (Rick86)
Based on the choices, I'm torn between 383 and 383 :lol:
whats the dilema 3.75 stroke or 3.800 stroke :confused:

Re: [Poll]: Engine Rebuild Choices (vettes rule)
I've done the 383 route and the fully forged 355 route. The last one I completed was the 408 w/ the supercharger. I did this to be different and to make lots of torque/power without twisting it to very high RPM ranges. I would say that for all around ease, the 383 is a much better route. The 408 required lots of work to assemble and then lots more work to get everything right in the car. Now that I've said all that, I am currently in the process of building a much larger cube motor, again in the small block package w/ large blower package (for another vette). Go figure!
It's all in what you are looking to build. I do say this, if you continue to drive it like you have in the past (high mileage), I would stick to a good R/S ratio (like the 383). This will allow the cylinder walls to last longer and stretch the duration between overhauls.
Best of Luck with your decision.

Uhhh.. 3.8" stroke?? I think you mean 3.875 (which is a 396) 3.8 (which oesn't exist to my knowledge), is a 387.70cc

396 I'm a sucker for nostalga. The more cubes you got the more tame that radical cam your going to get will be. I found a 396 kit with a cola crank some oliver rods and srp pistons for $2095 :cheers:

Re: [Poll]: Engine Rebuild Choices (Mojo)
Was that a 408 using the 0.040 overbore 400 block and a 3.75 stroke crank? Or was it a 4" stroke in a 0.030" overbore 350 block? I have had no issues with cooling on the 350 block version.
Just curious.

Re: [Poll]: Engine Rebuild Choices (SurfnSun)
SurfnSun,
You must have me confused with someone else. I have had past experiences with Calloways, and have driven many ZR-1s (never owned one though). But if I were to buy one, it would either be a 96GS roadster (must have red interior), or something like a '02 Yellow (maybe white) MT roadster. Maybe one day. For now, I must just be content with the new engine build-up sans blower and possibly more mods to the '98 roadster LS-1. Already done heads, intake, and cam on the LS-1. Maybe the new LS-1 Procharger would be a good addition. But for now, no new additions to the family. Unless someone knows of a GS as described above ...
Oh, I did buy my wife a new '02 Toyota Sequoia (nearly the cost of a vette) a couple months ago for her B-day. Does that count?
