Have what appears to be an uneven burn pattern with BBC.
Removed headers this AM to have recoated, heat in front tubes destroyed
ceramic coating. Headers are Hooker Super Comp have run the new engine for 3 weeks about 1200 miles. Engine was broken in on dyno. not with these headers.
Looked at headers and front 4 tubes are light coloured so very lean on cylinders 1,2,3,4 and rich on back cylinders.
I am running this engine with Fast EZ EFI 2.0 on Edelbrock Air gap machined to match ports, no spacer.
I am also using Fast dual sync distrib with MSD 6AL box.
Is this possibly an injector squirt issue, intake distribution issue, spark issue.
I was wondering if a 4 hole spacer might help distribute fuel air more evenly?
Powerglide in 67 Camaro....... not much fun to drive, like driving in 2nd and 4th gears with a manual. I'm in Arizona, what would be a reasonable cost for a swap, cutting driveshaft , moving crossmember and calibrating setup and linkage etc?. I was quoted around $2000 for the job from a smaller local trans/repair shop . Is this reasonable? I've seen reman 700R4's for as little as $350 on Ebay.
Thanks for your help
Recently swapped Holley DP Performer RPM for Qjet and Performer 2101. This is on 327 461 heads SCR likely 9-9.5 to 1. MPG dropped in half around 5,6 city, expecting decent MPG from Qjet. Car is Camaro Convert, not heavy, PG trans, tall gears I think, even though I can't burn off the tires I should expect a good throttle response. Car hesitates and bogs opening the throttle at about 20MPH in st gear. What tuning experiments are there with Qjets. I'm sure economy and performance are sort of achievable.
First time to forum.........will be looking for help and mining knowledge of all things Camaro for starters.
First curiosity, took delivery of 67 Camaro Convertible in July in Mesa Az. Driving was OK, however, car bogged under load, does need tuning but.......
Have 327, ME code engine, formerly 210Hp I believe, now has edelbrock RPM performer and 750 Holley. If engine doesn't have head, cam, piston crank changes to this block, what's the best way to pep it up but maintain reliability and cruise enjoyment? At this point I'm intending on keeping the car as stock as possible, even though the donor engine was not a 275 HP matching unit. The original car is 6 cyl vin 123, with factory A/C, not working, another post, I would like to try and make this engine resemble L79 350 HP or so using probably modern equipt. like mild cam and heads if necessary, I know, I could do a 350 swap just as cheaply.
