PRIOBE With the weber set in the car and tuned correctly you should get a 20-30 hp and 30-40 lb of tork in the mid range. You should look at your exhaust system for back pressure. Cover the fenders well, slide the motor in and get it running
Then go take it on a dyno and recheck the numbers. If you put the right numbers in the Dyno 2000 the numbers are pretty close, Mine was off by 8hp and 14 lbs tork. The real test is a 1/4 mile run. I hear all these huge numbers and have not see 1 cobra run 9's yet, THIS IS A STOCK BODY WITH NO 4 LINK suspension. 10.08 so far is the record, NO POWER ADDED EITHER. I run 12.5 with my motor. 360hp and 466 tork after exhaust and flywheel changes. Webers are the best till 6500 rpm, after that the single plane with a holley will past you by. Holley is easier to work on, Webers look alot better on the motor. Choice is yours
