WOW close to 15000.00 in headers... Now that's some creative ciphering..... :roll: ....that is more than I have spent on my whole car and it runs over a second under the index and that’s with a standard set of 2 inch hooker headers with a merge collector.WOW ain’t that something. Looking forward to...

As far as the short block, what is a good inch pound number for a stock eliminator engine. Care to comment on the piston and ring package. Thanks for your professional input and practical experience to this thread. With the NHRA mandated stock ring groove widths (5/64, 5/64", 3/16" in my ...

Got it!

.....does anyone have any thoughts on what the old Crane hyd FT 274H06(or Elgin 1785) 218’/218’ @ .050”, .450”/.450”, tight 106’ LSA cam would be EQUIVALENT to when changing over to a hydraulic roller cam & valvetrain INSTEAD of a hyd flat tappet? What's your reasoning for moving to a roller pr...

Possibly related to Stock and Super Stock engines, the LS engines have a trick for increasing the preload on the lifters with longer pushrods. It supposedly makes the lifter act like a short travel lifter, increasing stiffness of the valvetrain and making slightly more power. Is this a trick that c...

i guess you tried black electrical tape mod on the QJet rear metering rod holes ? This is a better solution for several reasons. Danny Ashley is a smart, smart guy on QJets. It's a shame he doesn't do them anymore. His QJets are in high demand and rarely become available. I'm fortunate to have one ...

A big part of my program has been the Elston 4-2-1 headers. We were testing headers and had four sets on the engine during one dyno session. What we saw with the Elston's led me to further conversation with Calvin and further gains both on the dyno and at the track. Where we ended up is about 180 de...

I love playing with these carbs for my street car... always looking to find ways to improve the already-great Q-jet. To get things really right requires going beyond jets/hangers/metering rods. As you know, these QJets are pretty sophisticated...basically multiple, very controlled, air leaks. It's ...

Yes. We do a lot of work in that area.

Per NHRA rules, the valve train style must remain as original...no shafts if originally studs.

Back to work. A good title for this pic would be: Three hundredths for three bucks.

Looking very close at the pic of the secondary air bleed tubes... depth would matter, as does position of Holley Emulsion bleeds. Do class rules allow you to modify those tubes? I've got some thoughts.... The secondary air bleeds orifice/depth/height and the secondary pull over enrichment system ar...

I like that rear anti climb baffle, only noticed some aftermarket pans with those a few yrs ago. But those use a straight piece, I'll have to make mine sim to that one for the stock pick-up stock pan I'm gonna mod. This approach works well and offers some additional benefits. https://i.imgur.com/mh...

Does icing down a cast iron intake manifold help? -Can it hurt? -Is there a better way to approach this? -How do you address the QJet tendency to get rich at higher rpm? https://i.imgur.com/RaYUylUl.jpg Back to the pump to test fuels: https://i.imgur.com/aRDVUgpl.jpg Testing fuels may require moving...

Nicely done, sir.

I'd add a brace from the pickup tube box to one of the pump cover bolts...likely you've thought of that already. Also, how is the oil going to be bypassed?
