Re: Pump gas 496 hyd roller build and dyno test
"Yup, build an engine around a 3.08 rear gear and a regular old TH400? That's stupid and Vortech Pro knows it. But the customer pays the bills and you work for them."
"I just have to laugh at a guy who will spend this kind of coin on an engine and not change rear gears or the transmission. That has to drive a guy like the "Pro" nuts!!!"
Actually it was my idea to run the 3.08 gears, an excellent alternative to a OD trans when you have the power to pull it combined with a tight converter and a turbo 400, bullet proof I might add. Alan's 3720 pound fully loaded air conditioned 10 sec 3.08 geared driver Vette........

Re: Pump gas 496 hyd roller build and dyno test
I'll second that. That much power will still yank 3.08 gears well. My turbo car on low boost is about 700 hp and never had a problem with 2.73's! Made for an awesome street driver. Now have 3.42's and its not quite as highway friendly as i like. Even with 27.4" tireActually it was my idea to run the 3.08 gears, an excellent alternative to a OD trans when you have the power to pull it combined with a tight converter and a turbo 400, bullet proof I might add.

And i may be wrong but i think camkings recommendation in the one thread was a solid roller so figure 10-12 deg less for hyd and its somewhat closer to spec.

What's the seat duration?
I have a hard time believing you'll make 700 crank with that little cam with those heads.

Re: Pump gas 496 hyd roller build and dyno test
I like the 3.08! Many years ago I had to go 3.70 in my Vette to run high10 sec at 130 mph! I dont want to hear the top speed running out of grear at 7000 rpm in top gear! Way to fast in the plastic fantastic.
Pls remember the combo as Iam planning to order one to my 4400lbs Caprice when I sin the lotteri!
As always a nice build by Mark. Wanted to hear of a small cam CBB build a long time.
Not to hijack, but is there still an IRS?

Sweet street motor with a very reasonable price. Makes me want an American muscle car.
Purely curious about the business side: Do you keep these motors in stock? Or are they built to order?

Re: Pump gas 496 hyd roller build and dyno test
How much to build this engine carb to pan from scratch? Customer provides nothing but the coin.
I simply see an overdriven transmission and the rear gear it allows one to run as a serious rear wheel torque producer. Almost like a power adder off the line. Say you have 700 ft/lbs at the crank. The difference between a 3.08 rear gear and a 4.10 rear gear is over 700 ft/lbs. What would you pay to pick up that kind of torque where it counts?

Re: Pump gas 496 hyd roller build and dyno test
I myself do not run OD trans, they are heavy, the converter is heavy, they rob power, they don't work the converter, and the 3.08 gear really makes the converter work. Now in my case Im all about 4.10 gears and 8 inch converters and 30X9 radials in my own street cars, (http://www.trracecars.com/4foot.jpg) but some won't have it, thats when I suggest the T400 with hiway gears.
Sorry I cant keep engines in stock, Im a one man shop.

Re: Pump gas 496 hyd roller build and dyno test
Awesome results! You are the first builder ive heard other than myself that loves the TH400-3.08 gear setup for street instead of 4.10's and an od, most of the Pontiac engines I build love the load put on them especially when you are making 600tq by 3000rpm its a less expensive, lighter and more enjoyable package imho
Build it Once Build it Right!
