Understood Jeff. Maybe they should look at the pictures before commenting or suggesting. If some goodfellas pulled up in the campground and fired up a 454 with a hitman transmission hooked to a 17500 watt producer, in a Airstream Trailer. Id have to go get more juice at the store. goodfellastransmissions.com might have a solution if you have problems with the tranny...
I commented to Jim Stoltz by mistake. The questions were actually for you. Thanks Jim for the shout back.
Amazing fuel improvement. As to engine wear, the SAE stated that 80% of engine wear is from cold starts after long periods of sitting. There was also another study done by one of the University's that said to was closer 90% wear from engine starts after long periods of sitting.
There are prelubers on the market that allows you to prelube the engine prior to starting. If I get my last major engine issue resolved I plan on looking into a pre luber. You can also use it to pump out your oil with a hose for fast oil changes while standing with a flick of a switch.
The balance and blueprint engine work you did will pay off in extended engine life without a doubt. As far as the cam, I did the same thing on a 383 stroker following a joint phone conversation with a guy from Comp Cams and the a engineer from AFR heads. I wanted the lower torque to come on because the engine was in a pick up and weighs more. It work out perfect. Horsepower is great, but torque is what moves things.
A couple questions, did you go with a roller cam on your rebuild? and also the cam grind you mentioned getting the lower torque to come on around 2200 rpm's should be right on the money I would think.
With that in mind, if you go to the overdrive transmission, what do think your rpm drop will be?
Casey. No I didnt go roller. I didnt think I would need them because of the low rpm I was shooting for. But, afterwards I thought they would have more advantages from a wear perspective.
Thanks Jeff. I, too, think that replacing the radiator is the only option. Anything else is a band-aid. I'll post back with my results once I get that taken care of.
Here is something from another RV blog on the 454 starter relay. It seems some are mounted near the bottom of the steering column, some mounted on the alternator, some mounted on the passenger side chassis frame.
Another thing could be a starter relay in the start system. I know, never heard or seen a relay until my coach wouldn't start. I started with the starter. It bench checked good. I charged the battery and had it checked. It checked goo d. Pulled the starter switch and it checked good. Remembered about the nutral safety switch and this too is good. Ok, must be a bad wire. Sure enough, checked for continuity from safety switch to starter and didn't have any. Started pulling wires looking for the break. The selinoid wire went to a relay. The wire from the starter switch also went to this relay. Pulled out relay and it checked bad. Replaced it and all my starting problems went away. I have never seen a relay in any wire diagram. I have even goggled about a relay and nothing showed that fit what I had. Even the Chevy parts guy never heard of a starter relay until he looked it up, and even then, it was a first for him. Mine was located on the underside of a brace near my alternator. Read as not easy to see. Oh yea, I have an '83 HR Monitor with P30 chassis and 454. Sorry for the length, but couldn't think of a readers digest version.
