Yeah sounds like a 1 hour wonder motor. Title of the thread is going to be New Engine misfire under load low oil pressure help! Then there is going to be a bunch of guys telling him to check the obvious. Ignition carb fuel blah blah blah. I'm going to tell him his stuff is blowed up because it detonated and the motor needs to come out. After a month or so he's going to pull the motor. The builder is going to deny the warranty for some ridiculous reason other than he doesn't know what he's doing. The OP will either take it to another builder that's going to blow smoke up his rectum convince him how great he is and continue to take his money and build him another 1 hour wonder motor or the OP will get disgusted and sell the boat and part out what's left of the motor. How many times have we seen this happen?

Historically, the highlighted phrase is used in 2 circumstances.
1. Right before a notoriously bad plan is about to unfold.
2. Right after one promises not to finish on a Fountain skank's face/hair.

That's my queue to require all receipts of parts used in my engine from his supplier to him. If I trusted anyone in my biz bridges would fall!

Yes sorry ment to say Merlin block.

I think he is full of crap about the 5 weeks for liters because he said he would have the motor done in 6 weeks and was just buying time. Also said they cost $800 and crank is $1000. That along is 20% of the cost for the whole build for those two items. Dose not sound right to me. I guess just another bad decision on my part. I already gave him $5000
He gave me.

I agree

Dose anyone know what I should expect for $13,000?
He said 650 hp 589 CI. Merlin block, engine quest heads, not sure of the kind of intake and no distributor or carburetor and no Dyno.

Your engine builder wouldn't be Bubba's back yard speed and chrome would it??

13,000 is not out of the realm of reality for a BBC done at a shop.

Parts and hours add up quickly.

You should expect a well thought out and executed engine program with reasonable reliabity for 13K.

For $13,000 it needs to make 850hp and be able to go 300hours without even flinching. This guy is a total idiot if he plans on handing over to you a motor with no ignition, no carb and no dyno tunning. Any builder worth .02 cents doesn't hand a motor over to the customer not tuned.

It cost a builder about $10,000 in parts for a long block. Nice parts. That's with a good set of aluminum heads. Carb and ignition another $1,500. Labor for Machine work $1,000 is on the very highend for this kind of build. This is a bolt together kind of motor and should take no longer than one day to assemble the motor. A day on the dyno $5-600. That's $13,000 roughly. With the use of the Engine Quest heads take $3,000 of the cost of the build. Now we are back to $10,000 this is with new everything... But the builder has to make a living. $1,000 for assembling the Engine (1 day work).
