This is a used AFR sbc 355 stroker engine. It features high-performance AFR 202 cylinder heads and a complete rotating assembly, after about 500 miles it began to leak coolant. Crack in the side of the block in the coolant jacket. Cylinders are fine, it just leaks coolant I tried to weld it it is cast iron i dont have the skills to weld it. I have a second engine i don't know if its a 4 bolt main. Let it all go for 1,700 all internals new. Large cam shaft. Angle plug heads. Solid lifter roller rockers and rocker lock gurdles. Likes life at 5000 rpm. Just need to have a block machined to new parts spec. Aprox 500 hp very strong engine. I paid 3600 for the engine. The donor engine came out of my 67 camaro I dont know anything about it other than it ran when pulled much lower horsepower. Bad block. I ordered a new 383.I have video.of the engine running, it won't load on ksl. Send me an offer if interested .
