Thread: identifing 390 block early model?ribs

Tweet

i just purchased this fe engine, the guy said it was a 390, but he seemed very unsure, i was able to pick it up for 100, it came with a edelbrock streetmaster intake manifold, C4AE-6090G heads, a 600 4 barrel holley carb, some knock off chrome valve covers. i want a rebuilt 390, to put in my 65 ford galaxie and replace the 352 thats in it, my problem is i am unsure if this is a 390 or not, the pistons say 30 on them, and i cant find any numbers on the crankshaft. i am pretty new to this so i need some help, i found the numbers on the heads and took a picture of them, also i took pictures of the numbers i could find. also there are ribs on both sides of the block i am unsure what that represents but maybe someone on here can help me! and are the heads good or the manifold? was it worth my money? let me knwo what you guys think...
