Pontiac Automotive urban legends.

Where are you people getting your info?



HWYSTR455: I doubt you put 220K on a set of solid roller springs and make any power. I doubt you put 30k on a set.


I have them in SBC strokers. BBC street engines. Pontiacs, 572 cu.in BBC Merlin Jet boat. Thousands of Offshore marine engines use them. All aftermarket and running strong.
I give up. This is like the aluminum heads topics of the 90's when Pontiac people trashed the E-head when it was coming out. The posts are out there. I guess Pontiac people just want to keep their heads in the sand. Not my deal.

But people, don't trash or make statements about what you haven't messed with.

I'll be at VMP end of the month, driving my cart around in the pits watching all the Pontiac racers checking their lash over the weekend or **relaxing** between passes.

Just finished gasket matching & porting the CV-1 Intake. Stop by and take a look at the NEW Canted Valve CV-1 heads with a hyd roller, running I hope into the 9's on 93 octane pump gas.

Swear I did Dude, have records/receipts to prove it, now as for power, honestly, I don't remember, this was like 87 - 91, but can say the entire time it ran very well on the street, many in the area to this day talk about it. I even dug up the cam card, though couldn't find the spring info. I'm sure it was 'matching' springs, and the best available at the time. I spared no expense on that particular engine/build.

The engine was based on a 70 455 4-bolt block, 30 over, ported #62 heads, Crower custom forged rods, custom pistons, and was professionally built by an engine builder who specialized in building engines for racing P-51s through pylons. It was a fairly mild roller, 224/232 @50, .350 lobe lift, on a 112, which may have been the reason it lasted so long (using lower pressure springs). He may have changed the springs at 120k, but I don't think so. I let him handle the machine work, since A) he used the aviation machinsts that had high-dollar equip, and B) he was a Pontiac nut.

I ran two other roller engines after that, and both went over 100k miles, and I know on those I didn't change the springs. Those did show a drop in performance over about 80k miles though, that I recall. I was getting over 110k miles out of the hyd flat tappet engines at the time too, all under severe abuse (old habits die hard!).

PD - If anyone is having to set lash with a solid roller between rounds they haven't done something right... I set the lash on mine May of last year and have not had the VC's off since. I have well over 200 passes on it since then and it still runs the same and sounds the same as last year. 10.4's when it is cool, 10.5's when it is hot and muggy... this is a mild E-headed 462, cast stock crank, 6.625 Scat Rods, and I race on 104 and cruise on 93 - could probably race and cruise on 93 but I am a worry wart on stuff like that. Car weighs 3515 race ready and I run a MT ET Street Radial tire - I runnered up in AFX (Quick No-E) at Tulsa's Pontiac Race this past weekend and never have to work on anything - just jump in it, fire it, and go - walk around between rounds and talk to people...

And for whoever said E-heads run hot mine never get over 180 in the hottest weather...

Don't take this wrong - just letting people know a solid roller is not the lash setting nightmare some are making it out to be...

BTW - we just used your Shim Kit in my cousins 400 with 455 crank deal and it worked out nice
