Tell me what you guys think... I am building a new engine, but here are the specs from the last one.
My car weighs 2900 pounds with driver...
It hooks from 1.10 to 1.16 sixty foot times...
33x16.5 Tires...
I am running a 2 speed glide at this time.
The Engine was a 548" Standard Deck BBC.
Bowtie block which was pretty tired. It had seen some main walk, and had one or two head stud holes repaired. Block was filled with hard block.
4.25" Stroke Ohio Crankshaft
BME 426 Rods
Arias 11.5 to 1 pistons
Dart 360 Heads Ported and Flowed to 410 @ .800
Harold Brookshire .810 lift camshaft, Jessel Rockers, springs were 340# closed, 1000# or so Open.
Intake is a custom competition blower intake.
Blower is a 14-71 Littlefield High Helix with the Pie shaped opening.
40% overdrive and 38 Pounds of Boost.
Nitro Barrel Valve, 16 Injectors. We are running it a little rich, but safe.
Now I boke two rods in this motor a couple weeks ago due to an oiling issue... But this combo was used for at least 5 years and ran in the 7.60's to 7.70's in the 1/4, and 4.80's to 4.90's in the 1/8th.
This seems very slow to me compared to other cars with similar engine combos... I just read about a car over on Inside Top Alcohol which ran in the 6.30's with a PSI blower and Dart 360's @ 2700 Pounds. I also just saw an old chevy at a nostalgia race running in the 4.60's @ 3000 pounds, Dart 360's and a 10-71.
So right now I am in the process of building my new engine. I am running the same heads, cam, intake, blower and injection. Compression ratio is going to stay at 11.5 to 1.
The Block is a Solid Aluminum Rodeck 481T. It will either be 526" or 533" depending on how far I go on the bore. Crankshaft is a LA Kryptonite Billet, and Rods are Brooks 65 with Hemi wrist pins.
I am planning on running 40% over which should be again in the high 30's for boost.
I am changing my valve spring combo with a really trick set... They are capable of over 400# Seat Pressure, and well over 1200# open.
Should I see some improvements besides in the weight removed from the old bowtie block to the new aluminum one...
How much weight should be taken off with the new block?
Either way, the old motor was launched at 3000, shifted at 8000, went thru the traps in the quarter at 8300 @ 183mph.
Let me know what you think.... I think I should be going faster than 7.60's... Maybe it is the powerglide that is slowing me down????
