Cost to overhaul an LT1 short block If you had a well running Lt1, under 70K miles, and just wanted to freshen up the short block with new bearings, bolts, basically do a stock rebuild on it reusing all the factory internals, about what would it run about far as cost? Nothing is wrong with the motor and it runs strong now, but looking at doing heads and cam on it and may pulll it to change the pan and if it really isnt to much may want to freshen it up.

that doesnt sound to bad.....but while your in the motor why not beef it up....that is if your looking for more power....thats what I plan on doing, a 383 stroker and replacing alsmot everythign to beef it up a lil more to handle more power.
but 1000 doesnt sound to bad.

Shouldn't be too bad really. New bearings, have the stock crank polished(+/-$35), ARP main studs, ARP rod bolts, and Rings would do the trick. Run a hone down the bores, and put it back together. Basically the cost of parts, which isn't overly expensive. With the better rod bolts, and main studs, and fresh bearings your bottom end has a much better chance of holding up to the higher revs of the new heads/Cam setup.

A stock rebuild does not cost much. I say dont do it if you plan on spending money on it later for a stroker. Only 70,000 miles on it is very good. I have seen people throw heads and cam on 120,000 mile cars with no problems. Just choose a cam where you dont have to spin the motor very high to make its peak power. Keep the RPMs around 6000 and it will survive a long time.

like someone said eariler 70k isnt bad at all. as long as everything seems mechanically sound you should be good.
i put a cam in mine around 60k then changed again at 80k and now again at 90k

Bottom end is in good shape, it leaks oil from some of the common LT1 places, but that isnt a big deal since it would be getting fixed when I do the heads and cam. I prolly would want to build a stroker but that wont be for a very long time.

If you are thinking heads/cam than just do it in the car. Oil pan is a major PIA to do in the car but it can be done or just pull the motor and do it all
But I wouldn't freshen it up...

I should have the heads, flywheel, etc. off this week. I talked to the guy building the engine and he told me to bring it by next week. I'll keep you posted!

if you want to go past 7000 your going to need an aftermarket ecu.

I picked up my Race Prepared block out of a 96 Vette, its been honed and bored and zero decked. Bored .45 over. 398 cubic inches. Got the block for $450.00. Got Oliver billet 4 bolt main caps and ARP studs and bolts for free with the block. Not a bad deal

But 5700rpm is about all you need to rev a stock LT1 to, it runs out of power above that. You wont be able to get past 7000rpm with the stock pcm.
