Tech Question
jay pippin, hickory, MS, 1967 plymouth belvedere 318
Rick, I got a 383 out of a wrecked Road Runner that was about to be crushed at an old junk yard. The block #'s stamped are: E 383, 8-6, HP. The #'s on the heads are as follows: 1st set of #'s 86190, 2nd set of #'s are 2843906-1. Is this a high performance 383 with the 906 casting heads that are so popular and would this be a good engine to put in my belvedere II for a good street/strip sleeper?
Yes, it is a 1969 Hi-Po 383. All 383s 68-71 had 906s, the only significant difference between tthe HP and standard engines was the C.R. and the cam.
Actually, you may want to reduce the CR for street use (pump 92/93), and use later heads for unleaded capability. Vitually no HP loss with 452 or 346 heads. Or go with Eds.
For my money, I think I'd rather start with a 400. But not if I had the 69 383 for pocket change!
Rick
