Re: Building A Nostalgic 1970s Fuelie Headed 350 SBC

This is amazing. Beautiful engine by the way ! Is it going in the dyno ? Can you tell us more about the car setup the engine is going in ? Heres the good news- it will be dyno tested today. The car is a NHRA legal F/SA Chevy II, that has been put on the street, T350 8 inch converter, 4.10 gear TRRC...

Re: Gasser Cam

YEA ... I know what you are really talking about ... your buddy is probably right where he needs to be, at this moment. That is why I personally am content these days to merely go watch and help some competitors once in a while. Last Year I re-did an engine from a Southeast Gasser competitor because...

Re: GM 396 cylinder notches

I learned something i was not aware of ( the earlier 327 hi-Horsepower engines were 2-Bolt Main Caps) and that is good that i learned. I never have tried to hold a doctorate degree in knowledge on OEM data, but i definitely admire those who do ! . So with all the thrashing on the street and drag st...

Re: Old TRW piston clearance.

.0015" according to my 2005 catalog. Bill, are we talking about the same piston? I am talking about the old forged pistons that did not have the lightening bolt. I am 99% sure that TRW recommended .005. Maybe it was the max but I will look it up. I have an old instruction sheet if I can find it. Th...

Re: Old TRW piston clearance.

For them to be quiet .005 to maybe .006. A little noise on start until it warms up .007-.0085. If you have to use them because that is all you have .0085 to .012. I don't recommend really running more that .065 on a street engine. However, when you are young and poor and that's all you have run them...

Re: Bill Jenkins , Larry Meaux and header wisdom.

Could some of the differences stem from Jenkins working in a very narrow rpm range where Pipemax works over a much larger range? In other words, would the header be the same for a 331 in a powerglide super stock car compared to a 331 in a 4/5 speed stick that leaves at 7500, shifts at 9500, never dr...

Re: Stock Eliminator secrets?

And it pisses me off that National Dragster no longer publishes NHRA records. Before they dropped that ball, they listed the records but would no longer list the names of your crew or sponsors. I called them on that and I was told “nobody really cares about that stuff anymore”. Total BS! Before I r...

Re: Watered gas.

I'm putting this here because I figure more will see it is all. I have like 14 or so gallons of watered down pump gas for my lawnmower in say 5 small red plastic gas cans. Seems my airhead Son left the empty, open cans in the back of his P/U and of course before he refilled them so we could mow our...

Re: Too much valvespring?

The comp hi tech lobes, both .420 and .440 are very mild by a lot of today's more modern lobes. I have run them in bbc with 240 seat and 600 open with the same weight valves you have without any sign of float shifting at 6800. I really don't think you need that much spring unless the boost from the ...

Re: Tunnel Ram 4-Speed Bog

Put a 40 lb flywheel in it and get a clutch setup that will slip just a little. The slipper clutch will also help keep breakage down. For that small an engine to leave he has to launch it almost on the mat. You may need more timing. Some of the 283-292's we ran in the 70's needed as much as 52 degre...

Am I reading the chart right that shows the two step on 4500 last year and 3500 this year?
DA was slightly better, approximately 2700' on that one.
Thanks
