Holley Rebuild

i got mine from skidim.com last year. just call them and give them the number off the carb and you'll have it in 3 days. most people here will say to put the 6.5 power valve in instead of the 2.5 that comes with the kit. i used the 2.5 and mine runs just fine...

Thats a tough question to answer. Its going to be very difficult for anyone to guarantee a certain rebuild kit will work without knowing the carb's LIST number.

I dont agree with Doc's 2.5PV recommendation- comparing what works best on a modified 331 (302 based) stroker to what will work best on a stock 351w is an apples to oranges comparison.

Timmy do you figure PCM has a reason for putting a 2.5 in their kits,must be a mistake on the engineers part..........
Call Vince a Skidim and ask what the reason is, must be a packaging error or all their kits are used on modified motors.........

We are not talking about a Holley kit , we are talking a OEM / PCM kit. This is the kit and PV that PCM recommends now.
Of course they did no testing to determine this change.
As far a vacuum of my engine, this is a moot point, this is about vacuum at cruise and at the transition of the PV.
A little fine tuning or tweaking will improve most carb applications.Holley has a "fit all " kit that will work on most any application, not the perfect match but close.And from the threads you are satisfied with close, I am not. A though plug reading and careful tuning along with thinking outside the box will sometimes render superior results...
But Timmy you do with this info what you will and not shove your beliefs on others that may be misguided by your thoughts.......
And for the record have you tried a 2.5 in any of your many carbs you have built or replaced, I think not, ,,,,,,, Boat dr

Chris, I lost something in that last post..Did I miss something along the way, and if so please bring me up to speed.........

I will not question his knowledge on the training in Electical Engineering but I will ask where he comes up with some of his other

Here's my opinion:

The Stock engine will have less HP/Torque and therefore is under heavy load in a "displacement" hull. Remember, these boats are plowing water at all times. Load equals the need for a Power Valve and in my opinion a Stock engine needs a higher number, thus the 6.5.

A Stroker engine with performance adders has plenty of HP and Torque is less dependent on the Power Valve and that's why Billy get's away with the 2.5.

So my advice to the original Post is to buy the rebuild kit, but get one with the 6.5 Power valve.

Well you don't have to replace the metering block or have someone curve your distributor for you if you know what your doing. And you don't have to redesign the carb to make it work properly either, but then all you had was a hole shot and no lungs on the top end thats why yours was the slowest after 100 yards because it is tuned so well.

Sometimes you just don't tell all the tricks your Dad's been teaching you since you where five. Some people just do it, some can just look at things and figure it out, some learn best by watching, some can do it much better than others, others spend way to much money to have others do what they cannot Some talk about what others tell them instead of knowing it all ready and not devulging the knowledge. Some haven't been getting their hands greasey since they where five either, sorry I'm just not one of them, guess I shouldn't have been under the hood helping Dad at the garage make a living and should have helped mom with the accounting, Nnaaa that wouldn't have been any fun.
