I would venture that the reason for keeping the adjuster cup close to the rocker has nothing to do with strength.......but more to do with rocker ratio. The further out of the body the adjuster is, the more 'ratio' that is lost on the prod side resulting in lost valve lift & duration.

Jim, A tight LSA cam with less duration can also idle smooth, see post # 309.... & give more power. Since both cost the same, I will take the one that gives the bonus: more power. Cheers.

...that D. Vizard 'invented' tight LSA cams & that they were never used in production engines. Not so. The Morris Mini 850 engine came with a 230* cam [ adv duration ], 107.5 LSA. The low duration allowed for smooth idle etc. All of the BMC factory production cams were ground on 107.5 LSA. Some...

MSD DynaForce or any starter that is rated 3.0 hp or more. Be wary of: - a company that does not provide a HP rating for it's starters - cranking tq #s quoted for the starter. Useless. Just like a certain amount of HP is reqd to move the car, a certain amount of HP is reqd to 'move' [ crank ]...

Ant, Did you bother to watch the video of post #298??? You will learn a lot. I keep mentioning D. Vizard. He was contracted by Crane cams to do cam testing, which is where the 128 condensed rule originated from his cam program. At Crane, he tested over 19,000 cam combinations! When I meet...

...that max air flow into the cyl is going to be close to, or at max lift. A cam with a 110 LSA installed straight up has the exh valve at max lift 110* BTDC & the int valve is at max lift 110 ATDC. Why is that important? On the intake stroke [ more importantly at low & medium rpms ], the...

[1] If you are running a grd cable from the starter [ block ] to the battery, that will be part of the problem. Too much resistance, which causes a power loss. You should use the body/chassis as the grd connection. [2] I had a look at the TuffStuff website & two starters are shown for the SBM, a...

The initial body position does not matter. It is 8 cyl, so you have a choice of 8 positions. On some engines that use a vac adv dist, the VA unit may get in the way....so select another position.

Turk, You couldn't explain anything to anybody because you know nothing....

You really going to rely on 'Adv duration' numbers? The Chrys cam & the Pontiac cam have 225 & 224 @ 050. Their adv numbers are 284 & 301....... Or two Crane cams, both 273 @ 050, but 308 & 330 Adv duration.

Ant, Get DVs SB Chevy book, SA books #57. Money well spent. It has a couple of pages of cams, hyd & solids, FTs & rollers, from mild to wild, for various engine sizes. It gives LSA & duration for these cams & you will be able to make an INFORMED decision on a cam for your engine. I believe...

Ign type does not cause slow cranking. You need a high HP starter. The MSD Dyna Force is over 3 hp. Some companies make a range of starters, with some less than 2 hp.

3402, You are close to the 290 @ 050 limit, so use the 8 position method. Some people are making too much of this, almost anal. You have roller lifters.......& presumably roller rockers. A roller lifter has two areas that can vary in dimension [ that a FT lifter does not ]. How accurate the...

Post #15. Newbomb Turk. Wrong...AGAIN.

When advancing or retarding a cam, you are doing so in crank degrees, NOT cam degrees. So in the example in post #22, one tooth would be 15.8*. that is a lot. Yes confusing. Regarding cam timing [ in degrees ], the only number that is in cam degrees is the LSA. Every thing else, ICL, ECL &...

The 4 position method is accurate up to 290 @ 050 duration; more than that, the 8 position should be used. Once the initial adjustment/running in is complete, the random method is the most accurate.

Crower make stud s/s rockers.

If you guys think the 'US made' FT lifters are OK, then you should watch a few Powell Machine Co videos...

Clean plugs with Lacquer Thinner & toothbrush. Good to go. But why were they fouled? good chance it is that shiny thing bolted to the intake with 4 bolts.....

From Crane cams, years ago. To feel a difference, adv or ret the cam a MINIMUM of 4*.

I didn't read 36 posts. Mike Jones, aka Cam King & renowned cam grinder said a while back that the FT lifters are made off shore, only one company making them in the US. This week on Speed talk he said he has Chebby lifters.....for $320. So if you are getting lifters for much less.....they are...

So, no ign box, just a bal res? That would be correct for 1967....which is: ign coil, points & condenser. I would start by replacing the points & cond.

Might be one for the Guinness Book of Records....

Agree with RRR. More timing on an unloaded engine. Engine is NOT driving the car, just itself. Other thoughts: - there will always be some air trapped in the cooling system of new engines. You have to run the engine, let the engine cool, to push the air out. This may take 2-3 cycles. The engine...

Well Turk, if you are not reading what I say, & then posting bull ****....that makes you a bullshitter....

I stopped adding additives a long time ago..... I figured the oil companies know how to....make oil.....& if an additive was needed....they would add it.

Turk, Post # 106. If YOU were paying attention, I made no mention of T slot length....or width.

No wonder Holleys run rich. Carter carbs DO run a restriction to the T slot. Carter called it the 'Economizer' [ & patented it ] for obvious reasons. In many TQs I have checked, it varies from 0.046" to about 0.052". Another name for this restriction is the Idle Down Channel. In the Ruggles QJ...

What is in post #34.....I stated back in post #6.

Some ignorance about idle timing on this thread. 25* with a mild cam. The engine in question has well over 200* @ 050 duration on the intake. It has 9.3:1 CR. Consider this engine: 10.75:1 CR. 197* @ 050 intake duration. Note that, all else being equal, a higher CR reduces the amount of idle...
