I'd be bummed,  that's for sure. I'd get it out and get it on a RELIABLE dyno. Actually before I did that, I'd do a compression and leak down test while still in the car. Did the builder dyno test it? Were the heads on a flow bwnch?? If it does make the numbers the builder claimed, the problem is else where. I would also think 4.88's are WAY too much gear at that weight. 4.56's, or 4.30's would be more like it... This ought to be very interesting...

Are you sure the engine is in proper tune? Jetting. timing, valve lash, shift points, etc.? Was the engine dynoed? If not, I wouldn't give up on it just yet.

 I wouldn't give the name of the builder to trash them until you are POSITIVE it is lack of power from the engine... and not an issue with the trans or convertor... or?

Check everything that got changed from your old combo to your new combo. We don't know near enough about the motor to make any judgments what so ever. Same with the converter, or what headers it was dynoed with, then raced with. We need all the details to help. Did the compression go way up? What plug gap you running? Ignition system? Fuel system? Shift rpm? 4.88 and 31 inch tire looks to be too much rpm for 1/4. I calculate almost 8,000 rpm at 140 mph with 7 percent slip in the converter. The motor would be laying down long before 8,000rpm. You should easily be able to pull 140 mph with 800 hp.

thanks for te replys guys. yes i have done all of the above.the trans is new, covertor new.timing has been from 32 all the way to 40. carb is a 1050,jeting has been from 88 all the way to 98. was runing slower than that tiil we move the timing chain from retart 4 degree to straight up picked up from 10.50 down to 10.20 mph has been from 126-133. i have tried leveing 4000 to 5500 on the trans brake. the car feels like a dog out of the hole. no dyno on this motor .builder says he builds them all of time and he just dyno one that 807 hp and 701tq that is the same as mine.  he said the heads flow 370ish .i will be taking this motor out today .
What did your leak down show.... if you advanced it
the 4* to straight up, why not try going to 4* advanced
that will pick up the torque..... I wouldnt be pulling
the engine out yet

With my one recent bad choice of shops to deal with, in reading all this here are a few ????? Was this a new crate motor to start with or your old crate motor? What kind of shop would build a 15k motor and not dyno it in house to cover there behind? Ive learned real shops provide build sheets, dyno sheets, I hope im wrong but I hope when you start looking into the motor its got the parts it should have and what you paid for. The machine shop im dealing with now seems very top notch and they take time to talk to me, I felt bad thinking about asking them to make up a work order in detail prior to doing anything, but they were one step ahead and had one, they said thats how the business is run. Please keep posting on what you find....I hope its not from the flordia shop ive delt with, if so break out the pre-lube.

that pretty much sums it up. if it were mine it would be going on a different dyno soon.

Why would you... you can test more things while its
still in the car... more so than while on a stand
