Hello All,

Testing waters to see if there are any potential buyers.

Engine Details: 351w built as a 408w stroker with less than a 1000 miles built by Gromm Racing, San Jose, CA

I have the Engine Build sheet/Dyno sheet and video from Gromm Racing. The engine is for sale but it is currently installed in my classic mustang and was recently dyno'd & tuned on 5/6/22 by DeLeon Dyno performance in Santa Clara, CA.

Engine dyno HP/TQ Numbers from Gromm Racing: 522hp 6300rpm and 544tq 4100rpm (have the dyno sheet/video)

My mustang was Dyno'd & Tuned by Deleon Dyno Performance with final numbers: 460brwhp 6100rpm and 475brwtq at 4125 on 91 pump gas (this is with a TKO with 3:50 gears. I have video & sheet)

The reason for selling this is I'm going with a 4bolt main 427w stroker, I'm selling this from carb to pan, practically drop-in, and will fit any 67-70 mustang or 79-03 Mustang. 64-66 mustang or other platforms may take some modification, but best to do your research first.

the only thing that will not be included: is the clutch/headers/starter/Belt Drive System/water pump. (Timing cover is for reverse rotation water pumps 79-93 mustang)can also remove the intake and carb and shave a few hundred off, if not needed.

Please note - trying not to part out as a long block or short block, trying to sell this complete, the engine is 3 weeks old, less than 1000 miles, and waited roughly a year and 3 months to get this engine built. Never had an issue with the motor, no overheating, haven't raced the engine, the car is mainly for street use.

the engine will be removed by Mustang Fever, in Santa Clara, you can pick up the motor there once paid in full and the new engine arrives at his shop. We can coordinate on this.

Can provide a full detailed Build Sheet and dyno videos on request.

408w Long block details:

Stock OE 351w bored .40 over
Scat Forge Crank/rods
JE Pistons
Melling oil pump
DSS Girdle
Custom Grind Comp Hyd roller Camshaft 632 lift.
Morel Lifters and custom pushrods
CompCams 1.6 Ultra Pro Magnums
AFR 205 58cc heads
custom Timing pointer
Arp Hardware.
Compression is 10:8

Accessories (these parts are not new, they were used when I had my old 393 stroker)

750 Holley Carb had an electric choke setup but it was removed.
Ready to run Summit Dizzy (vacuum advance is locked out)
stealth Weind intake dual plane (The divider in the intake was removed to make it into a single plane intake for more power)
Canton 7qt Pan w/ dipstick
Black Ford Racing Valve Covers

The engine has the potential to hit 600hp plus with a better intake and headers.

trying to sell this local, I will not ship out of state or deliver to your door that's too risky and probably would cost more. I don't have a truck, unfortunately.

this is a great engine for someone who is not willing to wait on lead times from other builders. Happy to meet at a local cars & coffee, so you can take a look at the motor. My replacement engine is almost done so starting to advertise this one to whoever is interested.

Asking for 12,000 obo, also have a c4 that I'm willing to add to sweeten the deal, but will need a shift kit and a better torque converter if you are going to mate the two. If you are serious, feel free to reach out. Not in a rush to sell. you can view pictures here:
