My main concern would also be for the unneeded weight placing a greater load on the Rods.
Would you define the " unneeded weight" in this application?

Re: Dual pattern cams in towing applications

You wanna see some exhaust heat...... try a late production Mopar 400/440 with the pistons 1/8” down the hole, net CR near 7.7:1, and your typical 10deg split white box special dual pattern cam........ that’s too big and too wide. The ex manifolds are glowing so bright it seems like you can almost ...

Re: 355 Holden street engine

You mentioned you did a short grout fill. How much is that? What I am getting at is that I have read, (no personal experience on my part) is that a filled block, and I don't know how much fill, will lead to higher oil temps than acceptable. Like I said, I have not tried it but have a bbc 511 with 2 ...

Re: ANOTHER SBC STROKER QUESTION 377-

What would be interesting if one of the professionals on Speedtalk would rework his heads to get him where he wants to be. Their are a lot of pro's here. Speier-Carnut-Weingartener to name just a few. I doubt that it's logistically feasible for many reasons....but that!---would make for an interest...

I was always .03 or so faster with the shorter rod. Could not tell any difference in wear upon teardown.

Re: My BBC progress

The wheelstand was not a violent jerk in on the bumper in the first 20 feet. It was a slow smooth wheelstand that just kept getting higher due to increased power. There is a fine line between keeping the wheels down and getting the car to hook. The car was working good on the prepped track, did not ...

Re: Running hot issue, BBc

Back in my younger days I have a very similar engine to yours. Like you I had too much compression for the fuel I had. I raised a head gasket and lightly torched the head and block between the cylinders. The detonation also hammered on the piston tops and closed the ring land up on some pistons and ...

Re: Bang for the buck...goodwrench 350

Use the new lifters from the 204/214 on the Crane 266. Best I remember the 266 was ground on 110? The 210 duration will help in the towing rpm range and not hurt fuel economy, especially with increased compression. The new lifters/used cam should be fine, I have done it many times. As long as you ha...

Re: GM -140 “off road” cam

Granted the old 140 cam is not up to modern day standards. However, there are some positives that need to be taken into consideration before writing it off as junk. Back in the 60's and 70's parts were not so plentiful and easily obtainable. If you wanted to hot rod the only choice was your Chevy de...

Re: GM -140 “off road” cam

I’ve got a NIB Crane “Blueprint” version of the GM -140 cam and lifters that I have been packing around for probably 20 years or more. This is a solid flat tappet cam and lifters, 257/269@.050, .493/.512 lift, 112 lsa. Is this cam any good for anything? Particularly on a “hot street” pump gas 350 s...
