Re: L98 TPI 350 endurance race combination

It's going to be HARD to run with modern Japanese sedans... especially with their all aluminum DOHC engines, advanced suspensions and light weight... and that's without even considering fuel mileage and 'family car' fuel tanks. I would think a Honda Accord, Acura equivalent or similar offerings from...

Re: Building A Nostalgic 1970s Fuelie Headed 350 SBC

I love how guys think fuelies done right can't make great power. A well done set can be 260 / 200 cfm. A number the untouched rpm will not keep up with. Love this project! Thanks, Charlie There's a BIG difference between the 'typical' flat top 350 with double jump heads and a flat tappet 0.515" lif...

Re: Building A Nostalgic 1970s Fuelie Headed 350 SBC

I don't know how much to trust online calculators , but Wallace Racing Calculators calls for 430 hp to run 10.99@124 in the 1/4 at 2900 lbs. . Mark did say it was a NHRA legal F/stocker so it should be a well sorted chassis. just my .02 .Dan After reading the rest of the post, it looks like a much ...

Re: Building A Nostalgic 1970s Fuelie Headed 350 SBC

10'a seems like a HUGE stretch for basically a flat top 350 with double hump heads... and a cam with barely over 0.500" lift. That is, unless it's a 'pop can' on wheels with a ton of gear/converter and a well sorted out drivetrain/suspension akin to a Stock/Super Stocker. Personally, I think you'll ...

Re: Building an 11 second 70's nostalgic SBC

Just be careful with vintage heads. They are not as robust as new aftermarket stuff. They can be thin and problematic. One of my best friends got a set of 292's back in the day and carefully followed all the porting instructions in the Smokey Yunik 'Power Secrets' or whatever article it was in. I lo...

Re: Building an 11 second 70's nostalgic SBC

Just read the last couple posts. That's super nice of everyone involved! Some highly worked but currently 'outdated' old style heads would be ideal for this setup. It's nice to see people coming together to put some 'nostalgia' back on the road. With your guys help, this car will probably run pretty...

Re: Building an 11 second 70's nostalgic SBC

That "3600 lb " car will weight 3800 lbs with you in it. Which is it low 12's? or mid 11's ? Big difference in engine horsepower required @ 3800 lbs all in street trim to get there. The fast 70's era cars were stripped down weight to bare bones race ready weight 3200 lbs max. (under 3400 lbs w/driv...

Re: Block filler and antifreeze ?

Did it for years. I used Hard Block. No issues with the coolant. It will warm up and cool down a lot slower, plus you will see elevated oil temperatures. You will want to err on the side of a slightly heavier oil and install an oil cooler if you plan to drive it more than 10-15 miles at a time.

Re: D0OE exhaust port

Why does everyone always dogg the exhaust port in the SBF iron heads. With 2hrs worth of work they will be capable of making more HP than any thing the intake ports can do with a weeks worth of work. After working these heads on too many occasions the exhaust ports impress me more everytime. C5AE h...

Re: D0OE exhaust port

Walt, I need to ask, how does someone without a flow bench and some pretty good knowledge and experience " make them as good as you can"? How does someone without a flow bench know if there rework has taken a lesser flowing but smooth flowing port @ let's say .300" lift into being a gurgling turbul...

Re: Piston/Ring Question

A 3.0 mmm oil ring maxes out at about 13lbs, compared to 20 to 23 for a 3/16 std tension oil. They all back off a bit after they get hot. If you want, you can run a 9 lb oil ring....but there's really no point. The Total Seal Set for 4.125_1/16 1/16 3.0 is CR1002 and ships with an 11lb oil ring. Ke...

Re: Piston/Ring Question

We just had this discussion in the Advanced Engine section. Since you're already starting out with thinner rings and likely a low tension oil ring, I doubt you'll see very much difference. Maybe 5 hp over what you already have. https://www.speed-talk.com/forum/viewtopic.php?f=15&t=63226 Thanks. I h...

Piston/Ring Question

A question: I have a set of Mahle 4032 alloy pistons with 1.5/1.5/3.0 mm rings and a standard tension oil ring. The newer ones come with 1.0/1.0/2.0 mm rings, can be had in 2618 alloy, and I believe can be ordered with low tension rings. The engine is a 363 Ford (8.2 deck) that will be assembled thi...

Re: D0OE exhaust port

Better exhaust ports don't need as much duration to run good. Some guys used to shape those bosses into super sexy guide veins, it doesnt have to be all or nothing. Those exhaust port can flow 180 cfm or better without big outlet size. You don't need that much cfm for your goal but I'd make it bett...
