Re: Question for head porters

What is the hourly rate range that head porters charge, knowing it probably varies by location and job quality or do quote customer per job? What is the best way for you to advertise your porting service? Asking for a friend....... Really! Most "head porters" charge for a specific job to be done, n...

Re: 383 build for heavy truck and towing

For heavy truck with towing applications, I would concentrate on making the most torque at 1,200 to 3,000 RPM and take whatever you get for horsepower.
Part throttle performance and response is much more important than Wide Open Throttle. Any camshaft much over 200 degrees @.050" is to big.

Re: Holley 750 Dominator Booster Change Over

If you want to make it run well look over the following link. It needs t-slot restrictions, lowered idle feeds, and opened up angle channels to be ideal. http://www.motorsportsvillage.com/forum/viewtopic.php?f=6&t=3742 Thanks for the info on this but the 750 is a 2 circuit carb already so would I s...

Re: SBC intakes Holley 300-25 vs 300-2

Mr. Malik, Do you know if this one is 1st or 2nd version of the -2? Did both have the boss for the oil fill tube? My 300-25 does not. Dave That manifold in the photo is the original design before the changes. I don't remember about the other parts of the manifold other than the plenum and runners.

Re: Crankshaft balance by manuf, how accurate?

How accurate are the balance jobs done by the manufacturers? Looking at Lunati and Crower mostly. Internal balanced small block chev, somewhere around 3.6 stroke. Assuming I supply them with the correct bob weight and get everything right on my end, they should be good to go, right? Call them ... t...

Re: SBC intakes Holley 300-25 vs 300-2

All, How do the two compare? Is the 300-25 for the most part the same as the -2, except for a taller plenum, or are the port entrance larger too? Or is the 300-2 a lesser manifold altogether? If so, how mild would the combo need to be on say a 355 to make the 300-2 be a better choice? TIA Dave Ther...

Re: SBC intakes.

The 300-36 was released in the early 80's ... there were several single plane manifolds released around that time from different manufacturers.

With a true edge orifice oiling lifter the oil hole is above the annulus of the lifter. We surface grind a .002" - .003" flat on the side of the lifter body t...

I suppose that some people have done this so just how does an engine run? Say, a 4.60" bore one. Looking for stealth max BBC standard deck height engine size is all. I think it will be a 598" engine? Oh, what length rod do you use? pdq67 I have done this but, it is about the limit and needs to be o...

Re: rocker arm oiling problem

Walter, amc fan, thank you for the replies. Both comments lead me to think it may be a clearance or incorrect hole position. Amc fan, the man who installed the bushings did not remember exactly but thought .032 hole size. Thanks again, all advice welcome. Greg With only a .032" hole size, I would n...

Re: Holley 750 Dominator Booster Change Over

I have decided to take my 750 Dominator that is collecting dust and swap over to the new 12 hole Boosters. I got a set of the billet ones from Allstate and look pretty easy to put in. My Question is what jet to start with as a base line as I am sure it will be lean with the stock 750 jetting. I was...
