I blew the engine running up the grapevine on my way home to So. Californina. The chassis is an 83 model Chevy. Some of the shops in town say to replace the motor with the same type motor or just rebuild this one. Some others say don't rebuild buy a new one that is newer version of the 454 a series 5 instead of the series 4 that is in it. The difference cost wise is thousands of $$$. Any help on this would be appreciated.
Thanks,

I bet a new engine will outlive everything else on the RV - so if you're not planning on keeping it alive another 20 years go with whatever's cheap. One good thing about having the original rebuilt is you can pick a new cam for it that has some great low end for getting up to highway speed faster.
