MOPAR! Building a smallblock 365, forged rotating assembly, ARP main & head studs, Indy heads with shaft mounted roller rockers. The long block is nearly complete, just waiting on the cam to come. Likely gonna go with an edelbrock super victor EFI intake. Then comes the turbo, and still debating on running a small shot of nitrous (already have the kit). I think I could get over 800 HP, but I'll be happy taming it to 600-650. Should be nice going in a Ram SS/T street truck

I enjoyed doing it and of course the satisfaction of running them [^]
I always like cars and the faster the better when I was a kid if I could have gotten a top fuel car I would have done my darnedest to driver it around town [}:)]
I have a 69 camaro with a 468 I built years back .
honest I have thoughts lately of just a mind version just to cruse in
my street racing days were over 30 + years ago local drag strip is at least 50 miles from me
and the fact with money ( alwyas the case [:(][:(]) If I had any I could go buy a new shelby or hell cat to name a couple not including the hot rod builders and custom shops with all the creature comforts and drive cross country if you want

that's gonna be a monster. Keep updates coming.[^][^][^][^]
The neat 'thing' about the MOPAR small blocks is that they can be bored and stroked into the biggest of any domestic SB. The drawback is the head bolts that restrict the intake port size. For some reason, Chevy hit the mark back in 1955, with FORD coming in 2nd and MOPAR a distant 3rd when it comes to head flow. That's just the way 'things' turned out.
Nice Project though. The Blower in a Bottle might be a bit much, but HAVE FUN!!!!!
PS - it's the TORQUE numbers that I want to know. That engine will develop more Torque then HP under 5252 RPM and few like to be pushed past 6K revs.
This is 'Lumpy', my 2000 R/T And YES the shaker hood is real. He's only had a cam change and some tuning on the intake system and makes over 400 HP +/- 450 ft lb of torque at the rear wheels.
EDIT: Hard to believe I built this truck 15 years ago and my memory isn't what it used to be. Some 'other' performance mods were necessary to produce the power he does: Larger exhaust, No CATS, re-programmed ECU (he has two - one for pump gas and one for 'track' (100 + octane 'race' gas) gas. High stall converter and re-valving of the trans (neither of which increase power, but make launches 'brisk')
The RAM (any RAM) is a BIG hunk O' truck to push with a V8. Find yourself a nice clean 97-04 Dakota and really fly! I just picked up a nice rust free 2000 Dakota R/T (yes, they are still out there) to play with. It is my 3rd R/T and 5th Dakota since 1993.

Mopar got it right back in the day, with the hemi. Others, well...
I am very familiar with the Dak RT. I like this SS/T, its curb weight is just a bit less than a new challenger. I am thinking of another build already, when I pull the engine that's currently in the truck (100% stock, less some bolt ons), and find an old Ram 50 to put it in.
There is a company that does custom heads for magnums, fills in the bolt holes, redrills them, but it requires drilling & tapping the block also, and another thing: they're like $5k. If I were to spend that kind of money I would just do a hemi swap.
This engine will red line under 6500. I may or may not spray it, I'll make up my mind during tuning. I have a ZEX system already on the truck right now, so kinda thinking why not.
I have a 383 stroker in my Camaro that dynode at 540/515
Be VERY careful, if your tune-up isn't spot on and it detonated you will have a pile of scrap. Also the stock block, (if everything is spot on will be the weak link. The next one will be head gaskets seal. The SB Mopars only have 4 bolts around each cylinder, at high boost head gaskets seal can be problematic. You may want to O-ring the block and use copper head gaskets.
Good luck with the project.[:)]
Seriously, I would focus on getting the turbo dialed in and hope the learning curve for you isn't too steep
Whats your plan for fuel/ignition management?
Intercooled?
Maybe sell the nitrous and buy a meth injection?
after the idiot hit the truck last summer, the pinstripe was gone on the replacement fender, so i took it off all the way aroune and went from this
to this (still needs a bit of shading and highlights)

I just finished a 318 for my 81' W-150. '302 heads with 1.88/1.60 valves, small hydralic cam, (.441 lift, 218/228@.050, 114C. Performer intake, 750 Edelbrock carb, Gt-45 turbo. It made 520hp&633ftlbs.@4332rpm. I couldn't get it any higher as the wastegate and blowoff valves would open.

How many psi are you running?
Awesome.

I'll dyno tune it using an SCT tuner. Planning on running 60 lb injectors with a HiPoTek New Fuel Pump Module with Walbro 400 LPH Pump With Full Feed and Return System. Running through a 31x12x3 intercooler.

That was at 22.5 lbs. of boost. I dialed it back to 15 lbs. for street use. (All I have to work with is 87 octane and a Snow methanol injection system.) It makes 420hp and 500+ ftlbs at 14lbs. At that level it's still seriously taxing the torque limits of the stock 4spd.

Not all inner coolers are the same. If you have access to a 'flow room' or flow guy, you might what to have the inner cooler 'flowed'. Some are VERY restrictive.

I'm planning on running up to 15, this will just be a weekend and track play you... I say that now, but if I know me I'll likely drive it more than my hemi.
I bought the forged/studded short block used (3rd hand), along with a "built" 46RE tranny for less than I could've bought just a new forged rotating assembly. Got the machine shop to check it out, said the block and internals looked good, and that whoever built it knew what they were doing and used quality parts. New bearings and rings, block is good to go. Hopefully the tranny checks out good too, dropped it off so they can take a look and update what needs to be. The combo came out of a supercharged dakota RT.

I would definitely not skimp on your IC.
I see you're planning on 15PSI, if you go much over that pressure at that SCFM, it will create a lot of heat. Meth/water injection will knock those temps down quickly and it worth the exchange from Nitrous in my opinion. I'd suggest IAT and EGT gauges, cheap insurance for an expensive hot-motor.
But the rental car they gave me earlier this year was a Challenger RT Scat Pack. 500 horses. The name is fitting. It was a challenge getting that thing out of the rental garage without plowing through a wall.
On the interstate, once it got into top gear it IDLED at 70 mph. Excellent gas mileage cruising along at idle.
I punched it once on a stretch of street without a cop or traffic. Felt good being pinned back in the seat once again. Better initial shove than a jet in full afterburner. But only for a bit - the jet keeps shoving all the way to supersonic.
Had to skip to the bottom because all the techtalk is beyond me.

Yea, 485 hp & 475 tq gives a good punch, especially with 3.92 gears.
That manifold looks like a Torker manifold I used on a 69 RoadRunner. It was great on the low end for power but not so great on the high end for rev?s.

This single plane one doesn't really start making power til around 3k RPM's. Low end won't be much on this build, but once that turbo is spooling; it'll be a fun ride.
