Vortec headed 355

[Jameson]

Short block has about 3hrs of run time on it, pulled it from my car and picked up the vortec heads and started running with it until I got to the point that it will not be pump gas friendly. So time to change directions and cut my loses, I have close to 6000$ into this motor and most of the reciepts. Bottom end was built buy my machine shop. Currently the motor does not have the passenger side head installed so that I can show how clean it is and that it has not been run with the new heads installed. Will be assembled when purchased so that I can give the piece of mind.

2000$ FIRM!

Sounds like a good build.
As an FYI to potential buyers, I had a 355 that was VERY similar except it had the 11:1 slugs and I drove it all the time on 91 and had ZERO issues with detonation. I guess the head design helps with that? Just wanted to help plug it by saying that it will prolly be fine on the street.

11:1 on 91 is impressive! My Vortec 355 is 10.55:1 and I run it on 93 with no issues - it would probably be fine 91 too, but we don't have 91 in NY. Good build! And it should be very streetable.

No, It was built for my circle track car but never raced. I broke it in after building (1.5 hr) Drove it around to test clutch linkage and play with brakes around my house (1hr) Track roll in (.5hr) Then puked out a driveshaft and the car was parted... PM sent Doug
