AFR 225 too much for 382 stroker I think AFR recommends at least a 396 so there is not too much loss of low end torque. Anyone running AFR 225 on a 382?

I am headed that way also... last I heard Tony was too. May be worth calling him and asking how far he has got on his.

It looks like I'll be heading down the 382 highway also.

Guys...
225's would be excellent on a more aggressive 382-383 build up. I will be dyno testing the engine I am currently building (383 CID) and will hopefully soon be finishing up, the very first week in August. Lots of good stuff to try and share with you guys....the first test involves our popular small hydraulic (224/228) on the 383 short with AFR 205's (that should be an excellent street package for someone more conservative)....next, a larger hydraulic on the exact same combo (234/238 "Mamanator 2.5" cam
)....Then a head swap to a set of 225's with the same larger hydraulic stick and ultimately a street friendly solid roller getting slid in last with the 225's. That will be the the combo the gets installed back into my C5. I'm shooting for 510-520 RWHP in the C5 after getting her dialed in, but wouldn't be too upset with low 500's and good TQ....My 1.75 loooong tubes (LG's) might start becoming a bit restrictive in the HP dept. but will aid in this engine developing solid TQ numbers across the entire curve.
I'm looking forward to both the engine dyno testing as well as the chassis dyno testing to follow....Will of course keep you guys abreast of our progress and final results.
For anyone considering a 382/383 combo (and who's not in a rush), I should have lots of information regarding various AFR heads and cam packages to compliment that displacement.

As opposed to the all stroke 382 in discussion here, how effective would a set of AFR 225s be on an all bore 382 with a fairly streetable cam in the low 230s for intake and exhaust duration (weekend sunny weather street car that sees the track a few times a year, but mostly wanting as much RELIABLE power as possible)? Or would 205s be a better choice for this setup?

I have a 382 stroker with AFR 225 heads sitting in the garage, going on real soon. WIll post the results. I had them milled .036 and had Platinum PRC springs installed. Using .611/.619 242/250 114 cam, with FAST 90/90, and big exhaust.

All of this testing will be done at the same time. I have three days in a row scheduled for all the different configurations mentioned. Results will be posted shortly thereafter....Chassis dyno results in my C5 (in the solid roller configuration only) will be available a month or so later.
Thanks,
Tony
PS...Josh....regarding your question it once again come down to personal preference. The 225's will undoubtedly make more peak HP while the 205's will have slightly stronger low RPM grunt with a little more "snap" in the throttle...more ideal if you want to place the emphasis in the "street" side of a street/strip set up.

Just to clarify, my advice would be exactly the same to you whether you were building an all bore 383, or an all stroke 383. It's more a function of actual displacement, not how that displacemant is achieved. While bore versus stroke is a completely different topic (and highly debated), it's been my experience that the differences seen there in a typical street motor (not a highly tuned more exotic race engine) is very nominal at best. For someone condidering an "all bore" 382, my advice would be to stroke it as well and just build a larger shortblock (funds permitting)....It will make a bunch more average power than either 383 combo and you will never regret your decision to "supersize" your order....

If you go all bore get the 225's. I don't like the idea of using a 4.125 chamber head on a 3.9 bore. Won't the gaskets compression rings be right on the edge of the cylinder liners? That seems like it will cause issues on a long term basis.
