Re: ARE ALL sbc 010 BLOCKS HIGH NICKEL????
A few years ago I was milling a set of SBC 283 #896 powerpac heads to install rocker arm studs. Despite the fact both heads had the same casting number from 67-68 ( If my memory is right), one was harder to mill than the other. That was a pretty noticeable difference by the tool cutting sound, for ...

Re: Rod strength
Rods are designed to be strongest longitudinally in tension and compression. In operation, there should never be any forces exerted perpendicularly, so strength in that axis is moot.

Re: Hemi vs Chevy wager...
If one believes CarCraft/Motor Trend Road Kill, all one would have to do is pull a 5.3 LS out of the wrecking yard and bolt on a couple of eBay Chicom turbos, total cost less than $1,000 and an afternoon's work.

Re: Lash ramps for solid cams
Let’s talk about different ramp designs for solid cams . . . . Is it a true advantage to component life by running tighter lash ? Some random thoughts: 1. Why would we buy a cam from a cam grinder who had no clue as to what was the ideal lash for his lobe profile? If Mike Jones says, it's .0xy", I'...

Re: curious 1960s cam tech
Hi, Dan,
FWIW, this question came up on the HAMB a couple of years back and there were no definitive answers there either.

Re: Are these con rods worth saving?
It seems that the rods may have deformed a bit. Not necessarily. With that kind of mileage there would be extra clearance and the shells would have experienced some kind of mild 'hammering' in operation ...... not enough to spin 'em but enough to take the spring out, it's not exactly uncommon. As s...

Re: Small Diameter Wrist Pin Life
To understand what pins need to look like to withstand pressures, spend some time looking at OEM diesel rods and pins. They're always large diameter, thick walls. When that's not enough, there's aftermarket tool steel, $65 each: http://djprecisionmachine.com/wp-content/uploads/2016/10/5.9Cover-600x6...

Re: Race engine vs Street engine with same combo
I just don't think many realize how efficient the shortblocks are in those engines. Interesting debate, Chad. For the sake of discussion, on the 358"s in question, estimate a horsepower gain from the efficient short block versus just what we'd put together for our typical line-honed-mains, square-d...

Re: Best Gen 1 SBC main bearing thrust oiling detail 4 manual transmission
Suggestions? . . . for a street car with a fairly heavy clutch? This from an old school guy, but one who no longer uses heavy spring pressure plates. There are so many better, less damaging, better driving options today; twin-disc, centrifugal assist, et al , I'd recommend he choose one of those op...

Re: Race engine vs Street engine with same combo
Thanks for sharing that very interesting comparison. The additional 140 hp from just cam and compression is more than I've have given as a WAG. Suggest a very good head/intake/carb setup to take advantage of the additional lift and duration.

Re: Component Advice for a Vintage Racing Engine
Know a cam grinder that can grind the taper off of a cam so it can be used with roller lifters and am wondering what the center-to-center distance is for Chevy lifter bores. If it is really close to the Volvo dimension hopefully the link bars that come with the lifters can be used. It's a bit more ...

Re: Rod side clearance oil squirting?
On an inline, the slots are at the top of the rods, but some older V8s have a slot coming off the diagonal.

Re: Relocating brake master cylinder off firewall
You're pretty far down this road, but next time, remember, with the proper selection of brake components, power-assist brakes are not an absolute necessity on a car as light as your Chevy. I have several Studes out there running without and they stop quickly and easily.

I wasted some of the best years of my young life trying to make those buzzing little anvils go faster. :D :D :D I hear you on that British stuff... Only slightly OT, my first venture into carb tuning came after installing megaphones on a '67 Triumoh TR6 650 and it went slower. When I went back to t...
