Engine Rebuilding
 

What would be an average cost on rebuilding a stock 7.4 motor with preexisting issues... Thanks

That is a very tough question to answer. Too many variables and not enough infor

yea I know... I just got quoted for a 30 over bore and a balanced short block with no rods and crank for $4500 that seems a bit high but I could be wrong no cam or head work either

Between $1800 to infinity. Basic rebuild covers:
1) Head rebuild i.e. valve job, resurface plus parts if needed (Valves, guides, springs extra)
2) Bore and hone block
3) Recondition rods
4) Polish crank (add $100-$150 for turning)
5) Assembly
6) Basic Parts i.e. pistons (cast or hypereutectic), bearing, marine gaskets, head bolts, oil pump w/ screen
7) Clean hot tank

The options from there are endless

New lifters? Flat or roller? No valve job? Dressed motor or stripped?

Thanks guys... I know that there is so many options I made a few more calls in I think I can get done for a much better price . Thanks

Be careful, get what you pay for may come into play.

Oh I know... I am not trying to be cheap ... it never works out in the long run. I just feel that I could get a good rebuild for a little less. I been talking to Bob at Marine Kinetics he feel the same too..

The weak link on the BBC (the 330hp version) are the heads. Look into Dart Iron Eagles and a roller cam. I have them and an HP500 intake and carb- make 475 hp on the dyno. I am .060 over too.

Yeah, $4500 for 330 short block is out of line. Now if they are adding billet main caps, line boring, decking, deburring, honing oil galleys, etc... But you are far from 330 territory then.

Wannabe,
WHAT CAM ARE YOU RUNNING? THANKS

You can buy new oats - or you can buy the oats that have been thru the horse -- they come a little cheaper

Does that price include removal and installation?

Who ever you go with, make sure you get the agreement in writing so everyone is on the same page. Lots of shops out there think they are #1 and come to find out once you audit their work they don't know WTF they are doing.

Good luck.

That seems to high from my perspective. I would say $2500 - 3000 depending on pistons used would be more inline. I would talk to your local machine shops and see if they can do the complete short block, they are doing most of the critical work on it anyways.

When looking for someone to rebuild a motor for you, the following adage applies:

Good, fast or cheap - pick any two. ;)

A Crane cam. Sorry don't have the card at hand. It has a decent idle, hydraulic not to radical. Tyler Crockett picked it. Max out at 5400.
