Yep, can be hard on the trans if your in 1st, I use the original valve body but with a TF2 shift kit minus the high gear restrictor as I run 15 springs in the high gear clutch. The valve body has low band apply and I fitted a 16 roller 6 bolt sprag and billet front drum. I start in first (no...

Yes, was running 12.3's with a 1.95 60ft, the last run I let the tires heat up more so that it dragged the engine down on the burn out. Just getting a feel for the car at the moment.

So two years on I finally got to go to the track. Same combo as before but changed the crank for a new scat forged crank. I opened up the port runners and trimmed down the guide bosses myself, had a 30 degree backcut done on the intake valves and added some 1.6 mancini arms. 4.1:1 gear and...

Here's a comparison for you, 10.2:1 440 3.75 stroke, 850DP pulls just over 13" @ 900 with an xe275hl Hyd (231/237 @ 50 275/287 seat timing .525 lift). Same engine with a EX282S solid 244/252 @ 50 282/290 seat timing with .520/.540 lift - pulls around 11.7" @ 900. Both on 110LSA. The 275 cam had...

King do 0.001" either side of standard for BBM. Scat also cut the rod journals at low side for their BBM 3.75 crank.

Thanks, not planning on guessing, just want to know where is best for the adjuster to be. I would imagine not more than a couple of threads showing below the arm.

What is the ideal number of threads showing on the adjuster for the mancini 1.6 rocker arms, 440. Need to order some pushrods, thanks.

Thanks for the heads up on the Penrite, and yes we have that here. matter of fact Supercheap has the 10w40 full syn on special for 29.99 for 4 liters, I ordered a couple of packs for my daily the other day.

Thanks, good to know, what is your opinion on Dino vs synthetic for older engines. I know a lot of guys stick with what they have had good results with, what is your preference.

I don't know of any synthetics that have a high content of zinc and phosphorus, maybe there is but I haven't seen or used one. From what I have seen synthetics use other products such as moly and calcium in their HP package, mainly I imagine as high levels of zinc is not compatible with...

I'm sure that is sound advice, and what has been said for some time now and something that has worked - for the most part, FT cam failures still seem to happen regardless of oil, correct break in etc. I could offer up examples of opinions in favor of synthetics, one from David Vizard, renowned...

I ran a synthetic oil (oil extreme) for 6 years with a XE275HL (904 lifter) cam, 120 seats, 295 open. Can't recall the zinc/phos content, something like 800PPM. The cam showed no sign of wear when I took it out. There is plenty of thinking online that a good synthetic will provide the...

The comp XE cams are cut for the .842 lifter, the XE-HL is the .904 lifter grind as Beanhead said. XE274(842) - XE275HL(904)

I ran an XE275HL in a 440 for 10 years with no issues, when I pulled it looked great with no visible wear. I changed it for a solid to work better at the track with a set of 4.10 gears. The XE275HL laid over about 5500RPM in my combo. It did kick up a bit of noise which is typical with that line...

Don't be tempted to over tighten the hold downs, doing so can run the risk of ovaling the shafts and causing a bind on a rocker.

Overhaul on a 727 ain't that hard, with some reading and good advice along the way it is within the reach of most. It is a good idea to have some info regardless, I would advise Carl munroe's book on the 727 and the FSM.

The 71 sure grips were a 489 case, they have the thrust block and are fine to run greens and the thrust. The 742 with buttons may be different I am not sure. I run greens and stock axles with the thrust in place in my 71. The axles seated down and I have had no issues. I also confirmed this...

If you have stock axles the thrust will be fine to be left in there with the green bearings but after market axles can be longer and cause an issue.

I swapped my 12" for an 11" b&m holeshot 2400 on my 71 440, the 12" flashed to 2200 while the 11" went to 3200. I also added some alloy heads, cam etc at the same time so more power against the converter but same engine stroke. The 11" drives fine at light to medium loads but is a bit mushy at...

There are two bellville springs used in the 727, pre 74 and 74 and up, the later spring is a better design, more beef to it but it is flater, the pre 74 piston will work but it is best to use both the 74 and up spring and piston together, the later piston is taller, I think .830" as opposed to...
