Are they magnum or LA heads? Will they work with dome top pistons? I am impressed with the results you got.

Hey Brian, great job on the motor. Tens on a juice cam smallblock is hauling the mail in my book.

Really nice job! Brian!!

very nice , the 60' times are way better than the ET shows though.

Awesome running combo. Out of curiosity, what kind of vacuum did it pull at idle?

Brian, just sent you the pics from last night for a little bit of proof and to answer all the replies, yes the car ran great for a "low power pump gas street motor". So, If anyone is looking for an inexpensive street engine with great potential, give Brian a call.

I am going to let you say it is a 10 second car. That happens to be EXACTLY what the Valiant runs at Irwindale. And , guess what...........

Oh yeah, that "IS" a great Motor. I would seriously consider buying one if I was in need.

Great Job Brian!

sounds real nice!!

That sounds like something I would be interested in myself. Those heads work with the old 340 stock replacement pistons?

the 6.90's and 7flats wouldn't be too impressive for a 410 UNTIL you factor in the unported iron heads and a hyd. flat tappet cam and pump gas. NOW that's impressive!

Rock on Brian! That is awesome to hear!!!!

Thank you guys very much! It means alot that you can see what we did on a somewhat tight budget considering the peformance of the engine.
Before we ever had a dyno, we built plenty of powerful street and track engines. How an engine runs down the track is MUCH more important than any DYNO #!!

This engine will be for sale soon too, if anyone is interested just PM me.

The heads are LA X heads, hughes shaft rockers. I did upgrade the pushrods to .058 wall 3/8 hollow rods over the hughes supplied 5/16 solid for a tech article about pushrod oiling. I used AMC hyd. lifters and took that time to reinstall the dual plane intake for the drag strip runs.

I'll be running it again on the dyno for a few tests soon and I'll post that info then.

I'm working on uploading and resizing pics and movies so it's going to be late before I get them on here but they are good pics and movies...thanks to Rob, Mark and Phil for the help and laughs!!

Like I said before, I'm not lighting the world on fire or anything but we now have good proof that our RHS heads can make very good power at a reasonable price.
I'd say that's pretty good for the ole sb mopar!!

I think the vacume at idle was around 7" at 1000rpm, but I set the idle in the car at 1200 and it liked that much better so at that rpm I'd say maybe 8.5"...

I might add that that cam (XE295HL) had excellent street manners in my 340. It would idle @900rpm all day long. A 10 sec street engine.....schweeet

Some pics courtesey of Mark:

My G'd out gangsta lean...LOL!!
