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.

Mike, Hedman makes the #68310 (1.5" tube convention style header) for the G bodies. Just looking at them, I don't think there would be too much involved in getting them in a Nova subframe. Hedman's #68311 is the same header with a ball flange at the rear rather than a flat collector flange. A set of these and those inexpensive OBX collectors could be a nice cost effective setup.

I've got experience with Schoenfeld headers and ran a set of their 1 5/8-1 3/4 steps with Performance Welding merge collectors last season on my stocker. Schoenfeld seemed good to work with as I ordered my headers with the collectors loose in the box, Maybe they could do a set of 1 1/2" for 'ya. -Al

After looking at videos of some test runs, gonna go for more rear gear. Found a brand new Richmond 5.57 for a super price, will be in before the weekend(thanks Doug Smith), plan to test this SundayMight be a bit much for 1/4 mile, but will surely be fine for 1/8. We shall see! Also got some OBX merge collectors, they are stainless so took them to a welding shop to get some tabs welded on.

Nice Mike

MikeMoller · 03-16-2015, 07:07 PM

5.57 gear helped, about .2. Only made 4 runs, still need more work.

Updates
So took the car to a lumberyard and got it weighed, had to add 150 lbs. Disappointing that it was that light. Also occurred to me that the drive shaft did not have much play, just barely could get it in, the ujoint had to be turned to get it in. Fortunately, it had the bigger trans yoke, so swapped that out with the smaller one just to make there is no bind going down track. Cut 6 inches off the collector to get total of 19. Thinking the 25 inches was to much and hurting mph. MPH is 70 at the 1/8, and 86 in the 1/4, seems like it should be higher than that in the 1/4.

Went to Dinwiddie/Richmond for a CCRA race, and only got to run 1/8. Run one was 9.39 @ 70.13mph. Went from 69 jet to 66 jet, changed timing from 42 to 40. Went 9.40 at 70.02. Had to leave it alone for racing at this point, won first round 9.40 @ 70.01. Lost next round 9.359 @ 70.25 (broke out-9.38 dial).
For the last run, left at 3300 instead of 3000 - it was close to overcoming the brakes - and up 100 rpm on both shift points -5300 and 5800.

60 fts ranged from 1.94-1.91, 330's 5.91 - 5.89.

Took the car to IHRA Piedmont race, it qualified last but I felt comfortable on the lights and it goes under about .1 for IHRA 1/8. which is good enough to race.
Won first round in the Saturday combo, redlighted in the second round.
Won first round in the Sunday race, but was late in the second round against Chip Johnson-really nice guy we talked afterward.
Got to get a few things built/changed and get some 1/4 mile testing in, since not sure I can run NHRA index in 1/4. Elected to pass on the LODRS in Richmond because of that, would rather spend the money on parts/testing. Tops on the list is headers, carb, and converter.

Way cool build. Good luck I'm sure you will get it under the Nhra index just keep, at it. I think cars like this are just damn cool!

MikeMoller · 05-12-2015, 10:00 PM

Well, modified some old MR Gasket headers 1 5/8. Extended the primaries 5 inches and attached OBX Merge collectors, throat 2 1/2 going out to 3 inches, collector length 8 inches from throat to end . SLOWED the car almost 3 tenths and 1.5 mph in the 1/8th. Went from 68 jets to 72 jets (as most said they had to richen with the merge collector) and had no change. Put the old headers back on and went right back to 9.40. Thought sure the headers would pick it up.

Thanks for the encouragement Ed!

Seems the car does not like my home made alternator mounts. Keeps throwing the belt or burning it up. Interesting, it threw the belt off so ran it without a belt, picked up almost 2 tenths-so ordered stuff from east coast auto electric -mounts,pulleys, belt -to get things right.
