Cost of engine rebuild?
I have a 77 vette that i want to have 400+ hp... Does anyone know how to estimate cost. I dont want to get ripped off by engine shop. What parts can be reused normally. Any suggestions/ personal setups and costs will help

Just picked mine up from the machine shop... $1250, included new pistons (.030 over), tanking, crank polish, engine rebuild kit, cam, lifters, valve springs, valve job, valve adjustment and assembly... Also had my old intake, valve covers, timing chain cover tanked and cleaned up... I won't be using these at this time, but I'll paint, wrap and store... I was planning on assembling the engine myself, but for $300, I figured a new torque wrench, ring compressors, etc would almost set me back that much... Just let the guys that do this for a living put it together for me... One less thing to worry about...
They have me pretty worried about initial startup and break-in... Explaining how modern oils don't have the level of zinc (and something else)... Said to find a ZDDP additive for initial break-in and use another can at the first oil change... Last time I rebuilt an engine was 1986 or 87, so never encountered this new phenomenon... I won't be anywhere near 400 hp, but thought I'd give you my machine shop costs... Rogman |
Its almost like asking a surgeon how much surgery is going to cost. Probably get close estimates however I would imagine until the shop tears it down, there is probably going to be hidden cost.

Here is a great beginner video for those of us that aren't a fan of reading. It is very very good video. Well worth the price.

Go look at the crate Performance motors at Pace Performance, in Ohio. You just cant beat those deals as compared to rebuilding, plus you get a GM warranty.

go with a crate motor and save yours, do NOT exchange it for the core price if you have a numbers matching car!

PS stock rebuild on mine was about 1800 total

my engine rebuild into a 390hp 383 stroker cost me $3500 complete (out of car, machine work, rebuild with a 383 stroker kit, new heads, distributor, cam, etc, and back in the car running). i guess it depends on where you live as to what you will pay. i did some research at the time (about 8 months ago) and to accomplish what i wanted with a crate engine from a reliable concern was close to $1000 more.

Thanks Tim... I was very impressed with their work... This machine shop came highly recommended from a number of folks in Vegas...

Rogman, I rebuilt my motor last winter basic rebuild much like you are looking to do, I did all the work myself except the machine work and spent around $1500.00. I went form the stock 190hp to just over 300hp with just some mild mods. The motor turned out great I couldn't be happier with the way it runs. Create motors are probably a better deal in the long run for some people but I enjoyed doing it myself and knowing exactly what went into the build...

I am in agreement with this post. I stay away from body work, don't like but can do some wiring, etc. But I really prefer to assemble my own engines. Being in the line of work I am in I do have access to precision measuring equipment and I have an excellent machine shop nearby and I have done a few engine rebuilds and build from scratch in the past. It really depends on where you are in the hobby. If you are looking for quick and reasonable then a turn key crate motor may be your best option. If you want the experience of building your own and knowing exactly what you have, and you have the time to spend, then you may want to consider going that way. As someone said earlier a SBC is not rocket science, they are not trivial but they are manageable and there is so much material out there to study, learn from and follow that it may be worth considering.

My rebuild is costing 5k. I took my original engine in for a clean and inspect. The 40 yr old engine was worn, but had no cracks. It had been apart before, but was still a standard bore and crank. I got an estimate to rebuild the engine using what parts were usable and an estimate to rebuild it using a new rotating assembly. I already had looked into crate engines and knew what the cost was to buy new.
I decided to rebuild mine into a 383, update to roller lifters, roller rockers, forged rotating assembly, stud the main caps, new aluminum RHS heads, new aluminum intake, polished timing chain cover, polished valve covers, new oiling system, and large capacity oil pan, and have them do the complete assemble. My decision was based on this. I would rather have the original numbers matching block in the car rather than taking up space in my garage. Also rebuilding my engine vs a new crate engine was still cheaper. You can buy low hp crate engines pretty cheap. Even strokers for a good price. But when you look into forged internals and blue printed assembly's the price goes up quickly. A reason I let the engine shop assemble it is simple. They do this stuff for a living. They know the little tricks. The cost to assemble was only $300, vs me taking several days to get it done and maybe overlooking something. Also , I'm overhauling the complete car from frame up. It has given me more than enough other projects to do myself. |

Thanks for all the great advice. I know i sound crazy but i dont care about number matching. I am not worried about resale or anything. When it comes down to performance and reliability is a rebuild better than crate if cost is the same?

Buy a crate. Then you don't even have to think about whether the engine builder really knows about what fits what, and if the parts really match up. Take the easy way out if numbers don't matter and you aren't doing it yourself. There won't be so many surprises in the costs either.
