Question 396 vs 383 stroker

presently my 67 has a 366 truck motor (which I plan to change), 4 speed 3:08 in the rear, I was thinking of replacing the motor with a 396 advance auto sells a rebuilt one with a 36 month 150,ooo warranty they also have a 383 stroker with dart heads with a year warranty the stroker is about a $1000 more which has more hp (street driven only as of now) what has to be changed with the 396 or with the stroker thanks

Re: 396 vs 383 stroker

jdbr1,
Can you post some pictures of your 366 while it is still in the car? Recently there has been some questions asked on TC about how hard it would be to install a tall deck (which a 366 is) into a first gen Camaro.
I have a 427 tall deck in mine, but it is mostly a race car.

To answer your question though, my opinion is to stay with a big block if your car is already set up for one. It would be more cost effective and less hassle. That is ONLY my opinion though.

Re: 396 vs 383 stroker

I am blind here, 366 small bore bbc or 396 (larger bore bbc) compared to Sbc 383... Correct me here, both bbc have the same stroke as the stroker 383? Other than seeing a larger and heavier piston on the 366 or 396, What's the advantage? Both would produce same torque? Not to mention the added weight.

Re: 396 vs 383 stroker

Well, there's always the "wow" factor. Everyone is always looking for a BB in these cars. How many people are ever impressed with seeing a SB sitting in there. Honestly, how many threads do you see where people are asking "how do I switch from BB to SB?", I haven't seen one yet.

Since you've already got a BB, it only makes sense to keep it. This way you won't have to buy any new parts.

My only suggestion is: why limit yourself to a 396? I would say go to a 454. A 454 will give you the chassis-twisting torque you are looking for, and it won't need to be radically hopped up. Plus, a fairly-stock 454 will work nicely with 3.08 rear gears, so you won't need to change them out.

Re: 396 vs 383 stroker

And to address the other post about why choose a BB over a small block-even when they have the same stroke-the answer should be obvious, BREATHING ABILITY. They may be same/similar in cubic inches but even a poor flowing BB head, will flow pretty close to a very hot (large) small block head. Airflow=Horsepower & torque.

I agree but I would get the 454ci BB unless its not a option.

Re: 396 vs 383 stroker

I'm typically a small block guy, but for this particular case, I think it would make sense to keep it big block since it is already setup that way. As mentioned before, you might as well get as many cubes as you can and go with a 427, 454, or even a 502.

If your car had a six cylinder in it and you were debating between 396 or a 383 stroker, I'd suggest the 383. If you were debating between a 454 and a 383, I say go with the 454.

While I agree that the big block heads flow way better, it's my opinion that the good small block heads meet the needs for a kick butt 383 but lack the flow needed to maximize power for the large cube small blocks. The big benefit of the big block head comes into play with big blocks at the larger end of the spectrum. Keep in mind that my opinion is not factoring in the cost of having to purchase the good heads for the 383, where the "souped" up 396 would be fine with good factory heads.

And yes, the small block rarely WOWs the crowd unless it just got finished eating a rat. Then it's, "wow, you only have a small block in that thing?" But that's a whole other topic.

Re: 396 vs 383 stroker

You know you can put that 366 steel crank in a pass block... I'm pretty sure the 366 tall deck crank is the same thing as a 427 pass crank...Yes??...

Re: 396 vs 383 stroker

Yes, lots of wow factor here.. We have an old Sonny Leanord 614 motor and I was just thinking maybe the same thing. Trying to tame this down with a nice hydra roller and some pump gas pistons. Heck, with that much ci I would think even lowest compression and the stroke alone would knock the car to obilivion , where ever thats at. Just a thought now.

Re: 396 vs 383 stroker

PLT-1,
Yes, the 366 crank is the same stroke as the 396 and 427.....and will fit right in a passanger car block (be sure to rebalance, of course)......Plus the 366 crank is a forged steel crank!

Re: 396 vs 383 stroker

tough bottom end , those 366 motors,, we used them on the farm hauling grain,, bad part was that the top side was a little weak , dropped many valves. Saw one flywheel come thru the floor.

Re: 396 vs 383 stroker

Remember that that $1500 for the 396 dosen't include the $500 core charge. They won't tkae your 366 as a core on a 396, must be the same engine. Now if you wan't a 396, for $1765 plus $300 core Advanced sells a 'high performance' 396. It's around a 9.5-10:1 engine with a bigger cam than stock ( I don't know the exact specs.).If you get your salesman at Advanced to look up a 1970 Chevelle, then use the 396 engine, there will be a listing for engines that come up. This engine is there. It's different from the one in their reman book.
