Basically a complete 1/2 mile asphalt oval track motor.

It's got some good stuff, 48 degree lifters, only a 4.03 bore so plenty of meat left (4.08" max) , complete jesel rocker system, 15 degree W2's nice valve gear, oil pan and race pulleys.

Hollis says just a hone rering and go which wouldn't be bad. I've always wanted an R block bullet proof bottom end to build a 'mild' 700-750 horse turbo with. Maybe a 3.7-3.79" crank D dish slugs and a ported Holley W2 pro dominator with a sheetmetal EFI blow through.

Dizusters early B smallblock sleeper really getting me stoked to do one.

Then again a streetable 383" W2 motor done up like a late 70's pro stocker with dual EFI would be really cool too....even if it sits in a stand for a while.

I know the Ford/AMC guys with 9.2 decks use a 4" stroke 6" rod combo but I'm thinking a destroke to 3.9" with the 2" '327' journal 6.125" rods ( I have a set) might rev a little better and bob a bit lighter too.

Talked to Hollis and maybe he and Larry Smith and I could buddy up on an engine masters motor with it...or maybe for another collective Moparts entry, who knows? It was worth picking up, even if i dont have any real firm plans for it. Couldn't pass it up. Worst case, resell it to somebody who needs it, I wont let it sit long.

Thoughts? ideas?

Sell that "junk" to me, thats a thought.....

LOL

I forget what the compression is but if you have
something to put it in and you can adjust the comp
to do a turbo... do it... I dont have the R-block
but do have a 59% 416 and its nice to have some
torque for a change... if the price is right I'd
buy it and put it in the race car

Yeah I bought all of it Mike.

A turbo slug on this freshened up shortblock with a turbo spec roller cam would make rediculous power and torque..... for not a whole lot of additional $$$. Its kinda what I've always wanted to do to a small block but was always a bit nervous about bottom end strength on a stock block. That won't be an issue with this bad boy and the combination of the bullet proof valvetrain (and with boost it only needs moderate RPM to get there) means it would be lots of fun for a long long time.

I talked to Bullet and they said 48 degree Flat Tappets are near impossible to get, however 48 degree and 59 degree rollers are the same cost...do long as I don't need much more than about 112 lobe seperation going turbo, I can probably figure out a work-around for that when the time comes.

That's good to hear. My 380 has a flat tappet in it now. I figured I'd have to go roller to get some kind of streetability in it when the time came. Good to know there available. Not that it really matters since I'd need to get one anyways but did Bullet give you a cost on one?

In case you go the 3.79" route, I have some in stock.

What size journal, Rod? I'd like to do a 2"

Just doing some rough calcs, should be able to crank 750hp at 370 cubes with about 15-16 PSI, getting stoked now

2.100" SBC

Rod

Thanks, Rod,

I'll probably offest grind this 3.58 crank to a 3.7 so I can use the 2.00" journal rods I have in hand.....unless it turns out the short block has some long rods in it on a 2.1" SBC journal (it's possible) and then I might consider the 3.79" route. I think a lot of Mopar circle track guys run super light SBC pistons with .927 pins (so the chance it also has the 2.125" mopar pins trimmed to 2.1" SBC isn't much of a stretch)....so let me see what combo is inside first.

I've heard of guys getting some really strong flow numbers out of the 15 degree heads, the jesel gear will really give me peace of mind turning up the wick.

The oiling in the R blocks seems so much better than the stock blocks, I'm thinking the MRL roller lifters should drop right in.

Sent a PM to Dizuster, really warming up to a Turbo build.

What happened to the Power Adder Forum? Don't make me go to YB just to find some Tech anymore!

If I wasn't so old and set in my ways I would play with one of those turbo thing-me's too.

9.20 deck dry sump block? the whole small block R block scene confuses me enough without adding a turbo into the mix. Fascinating engine you have there.... assuming some series with an iron head rule.

No it's a wet sump but it was a 1/2 mile asphalt oval track motor that ran a 2bbl

Update:

Turbo may be on hold, we (Hollis Page, Larry Smith at HP Engines and I) may be entering the Engine masters Small Block Challenge on 2016 using all the "good stuff" as the foundation. We're scouring the rules to make sure everything here will comply.

They have a no motor plate restriction but this block is cast and pre-tapped (3 - 3/8" bosses) for side mounted motor mounts.

I'm familiar with Larry on Facebook. It looks like he does some good work. What are the rules and goals for this contest?

Should be able to push 700 hp N/A only.

Back in like 2003 several of us on Moparts were involved in one of the very first Engine Masters contests, it was a lot of fun and for all of us who were involved, we all got to know eachother really really well and all learned from one another, no egos, no bickering...disagreements??? Sure we did but we talked them through....respectfully like buddys over a beer...really fun times. Miss that.

This may be another chance to do that...if the Moparts community wants to come together and help, I'm up for it.

Larry Smith has sooo much ( 30+ years) experience with top tier 358" Nascar motors and Hollis is such a meticulous builder and he's been to the EM arena before....so it should be Really interesting what we can come up with. Larry will know just the optimum runner size to run.

I have a Holley pro dominator W2 that I think we may try with a custom sheet metal top for the ( rules governed) single 4150 carb. i have a couple nice pro systems 1000HP carbs in hand too. I think we can make near 700 with the 15 degree W2's, whats gonna be tricky is to get it all in by the 7500 rpm rules limit.

Most hp/tq per cube average wins.

What's cool is we have most of the key hard parts already in-hand. Inthinkmin the right hands an old school W2 can hold its own against the modern LS and Hemi in terms of hp/cube efficiency in the 370-ish cube range, especially with a rock solid 48 degree/jesel valvetrain and a bulletproof bottom end. It'll be fun either way, that's the main thing!!

It would be Wize to read the intake rules closer. J.Rob
