Tom, I agree that someone will make a BBO go fast at some point, but I am not going to be it. I have talked with several guys and like the idea of more gear as they can get the car moving quicker once they learn the limit and do not blow the tires off. I, personally, have looked at steeper rear gears and going to poly glas in the next couple of years ( I have to burn the current tires to the ground first!) :Brow: Realdeal, Sorry I was so mean yesterday, but I still do not believe that you get it. If you have a/c on your Hurst you must run the 'C' heads. If you take the a/c off, you must run the 'D' heads since that was the only head to show up on nun-a/c '68 H/O's. I have a blast running to the track with the car in tact, ripping off a mid 13 sec run, and driving back home with the a/c blowing cold. It was like that for me going to Stanton, 800 miles each way.
No offense taken Small. But I am not so sure. If somebody clones a H/O with a Cutlass will they have to run 5 heads? Nope. The rules state that exceptions can be made for parts that are no longer available (D heads). The Chebby/Mopar boys are running new replacement heads are they not? And once ported the C's will offer no significant performance gain over the D's. This car came both ways and the only significant difference was the cam. Sooo.... o No:
Mike I,am impressed with Greg,s car. It should get "Buick of the year" But when F.A.S.T. class is done and over with the lowest times and the fastest trap speeds will be set by a HEMI. Top fuel dragcars use a Hemi design engine because it,s the best. If a Buick or Olds, Ford,Chevy was better that,s what they would use. As for a purestock vs fast class I chose purestock. It cost 40% less to build a purestock engine over the other.NO trick cranks rods pistons cams to buy. The intials CEO don,t grace my office door at work. And I don,t own a machine shop. The money I save I can put towards my 70 ss Chevelle conv project.And get more "passes" at the strip. No ladder format! And there you have it. :moonu:
I'm not sure that's true, Rusty. I don't think the rules, or at least those that enforce them, look at how a car was optioned and how the factory built them differently depending on options. Heck, there are people running at the Pure Stock drags that don't even have the right year heads on their engine, yet they show up year after year and aren't told to not come back. As another example, I believe that an automatic W-30 can certify with the wild manual W-30 cam. Why? Because the NHRA rules don't differentiate between automatic and manual. I'd love to see someone build a competitive FAST Olds big block car. There's plenty of Olds enthusiasts out there who are capable of doing this. Unfortunately, most of the people who are into making these cars run 11s are not into the whole stock-appearing thing. Let's face it, people who are into FAST are odd birds by most peoples standards.
Maybe, but I enjoy seeing an underdog win....and winning they are! :moonu: That's fine ndrach. :TU: It's all about commitment.
Not too tough for a Certified Olds small block either :Brow: :laugh: :laugh: , is it Casey? Put those 350's back in your Buicks and bring em out! :bglasses:
Hey Iceman, I can tell you where you can get a couple of those Buick 350's cheap if you need one. :moonu:
Most of the racers who build serious Olds small blocks use displacements somewhere between 400 and 426 ci. But they're also using diesel (D or DX) blocks, which I believe would not be acceptable for FAST. I don't know if they could go as big with a gas block, or if the gas block just limits how fast they can spin them. Rumor has it that factory small block heads have enough meat in them to port them to flow as good as big block heads, so that shouldn't be the limiting factor in FAST. It's all going to come down to intake and exhaust manifolds. Back in the late-60s early-70s, NHRA Stock racers were spinning Olds 350s over 8000 rpm, right Dave H? But NHRA Stock allows headers. I wonder how 8000+ rpm worth of exhaust flows through log manifolds..... Oooops, I used the H-word within the context of Olds small blocks. Look out, here comes Dave! :rant:
Mine will spin 6800 RPM thru those "logs" with points and NO electronics ...... uzzled: Maybe I'm not "serious" enough .............. p
YUP. Mine also saw the plus side of 6500 many, many times with manifolds. In fact, that used to be the shift point. Nascar and DX blocks are spinning upwards of 8-9000 RPMs. Nick Jefferies in Iowa ran a stroked 350 standard gas block for many years in the low 10's in a 70 Cutlass Supreme w/o nitrous or any other boost. It was a stroked 330 crank. He now is running a big block as a temp until his Nascar block is done.
