I built a 350 Chevy motor for one of my local Mopar customers who bought a 1972 Chevy 3/4 ton 4X4 for cruising around on the week ends, no rock crawling, no off road driving or any kind of racing
I built him a 572 C.I. pump gas Hemi motor several years ago hence doing the Chevy now
I used a new steel 3.750 stroke crank with a set of 6.0 long rods and a Lunati hydraulic roller cam that is right at 224@.050 on the intake lobes and around 232 degrees @.050 on the exhaust lobes ground on a 112 LSA for EFI with a set of the small 175 CC intake port Trick flows heads and a set of their aluminum 1.6 ratio roller rocker arms. I used a Holley EFI Sniper along with their Holley Sniper ignition and with their lock out hyper spark distributor.
I used a set of Icon forged pistons made for a 6.0 long I beam SB Chevy rod from Speed Master, it has right at 9.46 to 1 true mechanical compression ratio, a little less than I wanted but I decided to leave it their due to it going in a heavy 4x4 and it setting a lot so the pump swill could, and probably will, get worse when sitting between use.
It made 427 HP at 5600 RPM and 434 Ft. Lbs. of torque at 4700 RPM on the second pull with out tuning with a 11.2 AFR at 3100 RPM to 11.9 AFR at 5800 RPM.
I didn't want to wear it out on the dyno chasing numbers that won't apply in the truck with the full exhaust system and so on so I had it pulled off the dyno after the third full pull and brought it home, it had a oil leak between the intake manifold and the front and rear sealing surfaces on the block, I had used a stock type OEM rubber gasket their which didn't seal up
I'll do the final tuning in the truck with him driving it
I'm going to be building a pump gas Mopar 360 LA with a 4.00 stroker crank and probably a set of Trick Flow 190 CC intake ports and hope it makes more power than this Chevy does

you are the man

Cab, i built a 408 dodge stroker using EQ iron replacement heads. Bowl ported with 2.02 intakes. Made 504 hp at 5700 and 518 torque at 4600 rpm running a Comp Thumpr hyd roller with 235/249/107 specs. A milder cam might not make as much power but will still shine! The heads flowed 276 @ .600 lift. I used an rpm airgap and TTI step headers, 15/8 to 1 3/4. 10/1 compression. Sold it to a guy 5hat drove it home 308 miles.

I was thinking of making a motor( with a 360 core) with a offset ground down to 2.00 rod journal size stock crankshaft that is right at 3.750 stroke, not the 4.0 like I would buy today, sorry I think it will be 382 C.I. also with a 4.060 bore and the stroke that it ended up being, maybe not quite 3.750, IE 3.742 or 3.747
That Chevy made 1.12 HP per C.I. so if the 360 does the same I'll be happy with that

Cab, that Lunati SBC cam, if you put that in a B-block 383, wouldn't the B motor make more power at a higher RPM than the Chev ?

The bigger bore and shorter stroke in the 383 with similar heads and cam would probably make peak power higher like you say
I'm sure that same grind on a BB Mopar core will have a better lobes due to the lifters being bigger diameter
The Chevy cam was ground on a 112 LSA and I installed it at 106 on the intake lobes so it is advance 6 degrees, it idled fairly decently at 900 RPM with 15 degrees advance and it sounded good, not big, but way better than a stock cam idle
I thought about using a set of bigger Trick flow heads but decided that him being a show car guy and it going into a 3/4 ton 4X4 pickup I would use the smaller heads for better low end throttle response

On an Engine Power episode they build a 410 stroker SBM with the Trick Flow 190 heads. In the episode they show an in house Trick Flow dyno video of a stock stroke 360 making 499 hp and 457 torque with their 190 heads. Here's the episode that has the Trick Flow clip:

This stock stroke 360 made 530 hp with Trick Flow 190 heads. The short block sounds pretty tame, but the cam is a fairly aggressive roller cam:

Looks like you have a pretty good chance of beating the 427 hp SBC build with a stroker SBM and TF heads.
