I finally got my 383 pretty much all together and I had a question in reguard to nitrous usage on a stroked motor like that. I ended up getting a 5140 crank, 4130 rods, SRP pistons and GM's Vortec heads that I beefed up a bit to handle the new cam and such.

I was told that the SBC strokers couldn't handle the spray very well, is there any truth to this? Any real problems with maybe a 100-150 shot on that setup?

 

My 383 stroker takes it just fine. 700 at the wheels before the main caps broke. If you are running stock 4 bolt mains, my advice would be to keep it around 600 at the wheels max.

 

you should have no probs spraying 100-200 all day. I sprayed mine with no probs at all. I also have several customers spraying this much with no probs. As long as your internals are setup well and the shortblock is built correctly you should be fine..

 

Sprayed many a old small block, no problem.

 

383 strocker here to...
The main limiter you have is the srp pistons.I wouldnt go over 250/300 on those.

Thanks for the replies guys, but concerning limiting factors...you said the SRP pistons were limiting me at no more than about a 250 shot? Well all that together would still make like 670-700 crank horses. And I wasn't planning on making more than 600 anyhow.
