My son used to buzz his 383 to 7,000 with those pistons and iron heads. Only problem he ever had was spun rod bearings from lack of oil in the corners. Pistons looked great both times they were removed. The last time we sold all the 383 stuff so that someday he could build a stroker with the 400 block I found for him. Some day...
Thank you for the info. How long did it survive before the fun police came a knocking? I was gonna do a 400 block, stock stroke with trickflow heads but i had the 383 laying around and said whatever, max effort street 383 going in haha.
