75 Nova U/SA

Mike...love your build.

For some 1.5" headers, take a look at the Flowtech #11108's. Thery're a 'shorty' but not a block hugger style. They are long enough to get past the crossmember and with a few pieces of tubing could be lengthened. I'd try them first out of the box with a nice long collector extension.

Schoenfeld has a pretty good looking set.Either 1-5/8 or 1-5/8 to 1-3/4" step and reasonably priced. Quality much better than the Flowtechs too.

Hey Joe, Clem was always right about that, you do have an advantage with more surface area in contact with the gas pedal! I think Pat H. has a complete 283, with a 2 Barrel I would fit into U/SA with the 65. Anyway great job with, truly an inspiration. I have only run a Street Hooker Headers with my BBC , My thing will be to modify those at least to equal length and maybe a step collector, but that's down the line.

I believe the secret to unlocking a better ET out of this car is really basically in the converter and rear gear. Last year while talking to Lenny C. he had talked about rpm drop between gear changes and what the converter played in this. I've heard folks say rpm should not drop more than 500 between gear changes ?? While making a pass the Nova sounds like this drops significantly between second and high gear. Best results so far have been shifting about 5500. Does the 10% rule still apply for trap rpm ? Should the car run through the lights over 6 grand and some ? Still need to check the flash rpm for the converter too. What flash rpm would you recommend ?

I was trying to find a used set of these just to try, and was thinking the same about the collector - nice long one just for a test. I found this interesting article while looking for 1.5 tube headers.

Ron,
I looked at the Schoenfeld but the tube/collector dim's are the same as my hookers. They do have a 1.5- 1 5/8 and 3 collector step headers but they only fit 1973 - 1988 Chevy Malibu, Monte Carlo, Pontiac Grand Prix, Olds Cutlass, Buick Regal , and Camaro 70 - 81.

Hedman has a step header (68274) for a Nova like the Schoenfeld above, but it seems it is unavailable. I sent them and email to find out what the deal is.

Also looking a cutting the hookers up at the end and putting on an OBX merge collector, they are available on ebay $69 each.

Joe, Schoenfeld lists the 165 for:
Drag "Street Class"
Camaro 70 - 81 ¤ Monte Carlo 72 - 77 ¤ Nova 75 - 79
Will not fit Chevelle

Conventional Style Headers for Cars with Engine in Stock Location or engine set back.
Clears side and rear engine mounts.
Will fit straight and angle plug heads. Must use short oil filter.

This is such a cool build...very fun to read through!

A quick question for clarity.. in the first post you stated "The engine will be the 262 V8 rated at 165."

Then on page two you stated "Depending on the grill/year, it can run a 350 2v, 350 4v, and a 305 2v"

Just curious what the combo is?

Love the "different" cars and unusual combo's which is strange to say about a sbc! LOL!

Here's a chart that lays out the Stock classes for all the 75-79 x-body Novas. Mikes reference was to the fact that the only identifying difference from year to year is grille and badging, so you could claim a particular year for the body by changing to the correct grille and trim.
