Trying to make a decision on on drivetrain for a 68 Chevelle I'm restoring. I spoke with Mark vortecpro on a 565 BB build but I lucked into a 555 from Terry Walters Precision Engines that was built for someone who passed away before taking delivery - couldn't pass it up. Maybe the next engine for my Camaro Mark. Dyno numbers 692 ft-lbs.of [email protected]
and 665 HP @ 5800 RPM.
So that 555 puts out only 665 HP and 692 lbFt torque.
I looked around and found this:
I don't know what you have in it already, but as you can seeyour giving up 160 HP and 40 LbFt torque.
Probably but you gotta have an objective/goal and start somewhere. Looks like you can fit a lot of tire in a 67-72 a-body so I'd have a set of street tires and a set of slicks for the strip.
Converter is another key factor that I haven't even started to really think about. I really need to get the final dyno sheet, car weight, tire size ect figured out so I can start making some phone calls. Right now the engine has an 1150 Dominator on it and Terry wants to try a Holly Ultra XP 950 on it.
I hope you didn't put money down yet
or order the carb. What is going to happen is the bait and switch, your Dominator that you paid for is probably fine,
but then he'll send you a Holley Ultra 950 XP. You won't even get the parts that came with it, i.e.; no idle extensions
a carb that many tuners dislike and it's hard to tune. Runs well at a very high RPM range etc.
Don't expect any quality time after the sale. You're on your own. Hopefully he'll ship yours in a bag, unlike
what he did with my engine. You'll also see NOT FINAL on all your invoices etc. So he can change out whatever
he wants to give you.
From what I hear, guys like Mark (vortecpro) and Mike (Lewis Racing Engines), will ensure that you are satisfied
and will keep working with you to get the engine up and running properly.
Unlike Mister Walters and David Vizard.
Feel free to PM me your NOT FINAL build sheet and the Dyno Pulls. Remember these are paid for by you and you are entitled to them.
I am free to discuss the crap that Mister Walters and David Vizard pulled on me, etc. The other engine builders
typically keep mum, as it's not professional to bad mouth your "competition."
Of all the things that David and Mister Walters could have done to assist me, after knowing that I had
valve problems and still do--they've ignored me, played dumb, said they weren't going to use the same
people, then never returned my calls or suggested anyone they know who could help me out.
In my case, I got the double whammy, and engine that is finally running but not tunable for street use,
didn't follow DVs guidelines for parts that I purchased up front, then bait and switch parts on there that I didn't want
and still give me problems to this day. And a recommended "mechanic/hack" that changed all the electrical
that I did and then couldn't get the engine to run.
What ever you do, you do not want that Holley Ultra 950 XP.
Here is my thread about it: LINK
All the best for your engine,
PS - I bet your engine paint starts falling off and it's not painted at the back of the engine.
Mine wasn't. One of those things that got drilled into my USMC head...kind of like the following:
Did you wipe your rear end after defecating? Why? No one sees it!
That's the polite version.
