guess the hp of my new and improved 496 bbc ????????
Hey guys back again, I asked the hp of my previous 496 a couple of months ago and got some great answers.It was not as much as I expected
Well the welds broke off of the pan oil flap and got caught under the pump and lost oil pressure, it hooked a bearing, but I shut it down with mininum damage. Here is the new and improved version of my 496
gm block .060 over
13.4 to 1
dart 345's some bowl work, took .040 off the bottom to bump the compression
full roller (cannot tell it all) but around 725 lift both in and out
283 @ .050 at 110
single 1050 dominator on a port matched 454 intake
What do you think ?
Not dynoed yet , just done so we will find out soon. Going in the end of this week or next should be dynoed by oct 18 th

[quote="chevyfireball"]I'm guessing 850-900 hp. I had a 69 Camaro with almost the same set up and a 200 shot of nitrous and it made just on 1100 hp on the dyno.[/quWOW !!!!thats a pile of hp for that setup. Very well could be wrong but but that seems like alot. I have a 565 that pulls 894hp at 6750rpm with a cam that is very similar that was dynoed with a 1150 dominator.
