ported intake Question
I have a 434 small block that came with a elddy super victor 2925 & Holley HP 950 it ran 6.20 1/8 @ 112 mph and 9.73 1/4 @ 140 mph . the man I got it from said if I would go to a larger carb it would do better. well who do you know that does not want to go faster. so I bought a new 1050 Holley Dom. and a polished Brodix intake 1002 I put it on and the best time I can get in the 1/8 is 6.32 @ 111 mph. we went from 90 jets down to 80's and the 80's would only run about 1/2 track up and down not enough gas. I've heard 50 different reasons why it slowed down. the one thing I keep hearing is that the intake is polished for alcohol not gas. this intake as a mirror finish inside. I'm putting my 950 back on but I was just wandering if anyone could just help with this so I can learn from this.
The motor -434- 15.3 to 1 comp. [665 HP]
58 cc Dart Pro 1 heads
690 lift comp cam Roller
2500# car
P/G - 176
514 gear
I had a 421 w/ AFR 227 heads. and I ran a Dominator with a dart intake and it was sweet 675 HP
Thanks Andy
