lifter girdle

[buickthunder64]

just wondering if someone had some advise on these? building a new 455,has a block girdle and is hard blocked but I think I should of put a lifter girdle in too. Not set on what size cam yet but probably around .598 or .600 lift(solid) thanks

Is when it is too late.:E:

I think it would be worth your while, especially if there is a little core shift, but I'm no expert. The most it will hurt is add 15-20#'s, and the money to shell out. I would think the value of the block is worth the investment.:BROW:

What year block do you have? I would think based on the size of the cam if it is not a fast ramp with allot of spring pressure you should be just fine without one. I have run both ways with my stuff. The only time I had an issue was with a way aggressive fast ramp deal and we had big pressure on it. Car made a ton of power on the dyno and for three passes but the bores decided not to stay in. It was a 70 block and was thin should have never tried it with that block. Sense then we run less ramp speed but still big pressure, Like I said both ways no issue ether way. I think were they are the most good is in a roller application.

Thanks for the advise,i guess Im not sure how to figure ramp speed but i was leaning towards the TA308s cam from ta performance.The block is a 72-73 and when i tore it down the lifter bores all looked to be the same thickness.there wern"t any that were thin.

I have a 308s used with Matched Lifter's to the Lobe. In the Part's for Sale. These Cam is in good shape and Maybe has 10 Passes. Let me no

Good indicators of ramp speed is comparing the duration numbers at .200" lift. Along with the advertised, seat to seat and .050" #'s. The 308S cam in a non girdled block will be fine. Unless you have a lot of core shift with thin wall bores on one side, which doesn't sound like you have.

I used the 308S in a very good motor I used to have.......

No Girdle (Main or Lifter),.038 bore on a '70 block,No Fill.
Stock rods,Ross pistons(12.4 to 1)stock crank,ATI balancer,TA Intake,1050,
TA Roller Rockers,Hookers headers.
Heads were 260cfm intake,195cfm exhaust 70 castings

In my 3200+lb Skylark I ran 10.30's and .40's all the time and went 10.teen's and .20's in good air.

Motor saw 6400rpm regularly........Very simple,Very reliable.

THANKS this helps me. How about what to use for a windage tray now that theres a block girdle on?

Most guys opt for a custom pan once they get that far into one. Stefs etc. TA has a deep stock appearing pan coming out soon that I am looking forward to. I want two, and called the other day to order them when I saw them advertised. Only to find out they arent even making them yet!:CRAP: :CRAP:

Or at least thats what they told me. Maybe its a conspriacy!

But the lady who answered the phone was very helpful and polite. Cant say the same for the Paddock!
