Ok i have a 350 olds casting #395558 2</span> gold block with #8 heads i have also #4a &amp; 7 heads. I have a 307 olds that is an 86 running that only has 74,000 miles on it . i want to build the 350 with the parts i have. this is on a very very limited budget. Will the 307 crank fit in the 350? Does the 307 and the 350 have the same stroke throw and the pin and bering OD''s the same? What is the best build up that i can do ? I still have the stock pistons for the 350 olds.I dont know if they are the high or low compresion[img]smileys/smiley5.gif[/img] I hope that that some of the older people can help me. I just dont know much about the olds. me i am more a chevy man. This will go into a 82 Buick regal that was set up from the factory with the 307 olds.

 

Ok the 307 will work but still hopeing for the build up ideas
