Don Terrill’s Speed-Talk

It's got a scat "cast steel" crank it and I'm not sure what kind of rpm it can tolerate. I never minded turning a 327 or 350 up but the longer strokes kinda make me nervous. Also, I've never done it with a hydraulic cam, I've always ran solid flat tappet cams, this is my first hydraulic roller and I...

With the cam I have , comp recommends their 987 springs. Would I be better off going to a beehive spring? Will the spring locators I have work with them? I'm guessing they also make retainers for 10* locks that I currently have? I'm thinking of going a little smaller on the cam, lift would be about ...

LMFAO probably lol

Comp cams advertises that cam for 3,000-6100 rpm. I thought that sounded off myself. I also got the valve springs they recommend for the cam. I've heard several say comp is a little conservative on their spring recommendation on their roller cams.

Weekend warrior, I don't care about gas mileage or vacuum for brakes. It might get driven a couple times a month and hauled to the track. No heater box or a/c. I just want to run on 93 pump gas.

Thanks Mike, can I ask why the 110 lsa verses a 106 or 108? This started out being a cheap vortec headed 350 and turned into a little more. I started out buying stuff on the cheap, that's why I have that freak show 3k converter. It's nothing to brag about. I'm planning on getting whatever will work ...

So bullet makes Straubs cams? I didn't know that. I thought he ground his own.

I am thinking of giving camking a try. I hope he chimes in on this.

Sounds like your 7.55 is closer to mid lift, did you measure actual valve travel with each pushrod length ? and ideally you'd be blotting that against crank degrees.

No I didn't. I don't have a dial indicator or degree wheel. I need to get both.

I need a little advice as to if it would be worth changing my cam. I have a comp cams XR294HR hydraulic roller in it, still on the engine stand. Adv. Dur.

I tried a backset Harland Sharp out tonight. I used the mid lift method and came up with needing a 7.450" pushrod. However, the sweep pattern was about .072" wide. IMG_20230121_185926424.jpg Then I tried a 7.550" pushrod and the sweep got smaller, around .045". IMG_20230121_192550743.jpg I'm not sur...

Sounds about as vague as you could get. Shorter? I've not a clue as to what's meant by that although I can guess. As far as the Crower's go, it clearly described that the only difference in the rocker arm assembly is that the hole for the stud mount in the trunnion is located "x" distance offset fr...

I'm going to try to try one these this weekend and see how it goes. The way I'm reading the email is the difference between the standard and backset is .100". I assume that's center of the trunion to the center of the roller. Being that I'm so far out on the edge of the valve, this will probably wor...

I did get an email from Harland Sharp today. Here is what Randy said. "Our standard Chevy rocker is 1.440 long We make a short version that is 1.344 Long. Let me know what you think. If you need something in-between we can do that too. Randy Becker Jr. Harland Sharp / Custom Speed Parts" Sounds like...

STR 11500 is the part number, but I can't find them on their website.

Here's the link to them that STR sent me in email. It doesn't offer any help though except to buy. Lol
