Small block stroker guys

A rod decided it had enough and made an exit on my 340 Friday night at the races. Planning my next build and am looking seriously at a Bloomer Performance kit. Thinking if the block can be saved, a 422 would be nice. What rpms are you turning these? I have a set of W2’s (open chamber, race) that will get sent out for porting provided they are okay as well. They can be opened up quite a bit as they are not too far away from stock size ports now (has mild port work). Any suggestions or experiences? Thanks and I’ll definitely have more questions.

When I had a small 520 lift cam in my 408 I shifted at 6400 and ran low 10's. When I put the roller cam in it and my better set of Edelbrock heads I shifted at 6700 and ran 9.60's. When I built my 422 with a solid lift cam and ported 360-1 heads I've gone some high 9.40's shifting at 7000 rpm. Over the Winter I hope to upgrade to a roller cam and possibly a few more cubic inches

When i had a 408 with ported indy 360-1 and solid roller 268/272 680/700 108 with 11.5:1 compression it made peak power at 6800 so i shifted at 6800.

Ryan Johnson would be a good guy for you to talk to.

I agree talk to Ryan , I shift mine at 6500 but I m
On a stop to run mid 11s

Brett Miller would be the guy to talk to, not Ryan!!!!!!

Ryan is more than capable on any Mopar smallblock heads. Its what he does full time for a living. And has for a long time
Made my W5's fly, and a local guy who does very good work was extremely impressed by the work Ryan did on my brothers eddie heads after carefully looking them over.

Not sure where you get off bashing Ryan, Probably not a better resource in the country.

I shift my W2 headed 408 at 7100. It made peak power around 6800 but 7100 is where it seems happiest in the car. The cam and compression specs are similar to what Mopar Dave listed above. Here’s the Dyno sheet:

Both of those guys r great engine builders you won’t go wrong with either one

Maybe I need to spin my 416 a little higher since I only shift at 5900 and usually it goes to 6300 through the traps!

Can I please get experiences or advice on a 4.125” in a 340 factory block? Been reading a little on the oiling and cooling mods. I realize an R3 would be the way to go, just trying to utilize what I already have. Thanks again.
