882's to E-Streets

Hey guys, I made the decision to upgrade my 882's for some Edelbrock E-Streets 5089. My heads needed valve guide work and I wasn't about to put any money in them. I had Jegs price match the E-streets so I scored them for $848 shipped and they came with a free $100 Edelbrock gasket kit. Talked to Edelbrock and the Estreets now come with 1.46 springs rather than the old 1.25 diameter ones.

Also upgrading to a Performer EPS intake and Holley Street Avenger 670 carb.
Brown truck made my day :D



Pulled the old heads today, should have em installed before the weekend. :yes:

Exactly, I saved enough on this order between the carb and heads that I had money for a new Performer EPS intake - and I got a gasket kit to boot.

Rather than having random sales and gimmicks, I think price matching is the way to go. Jegs has my business.

Ok, back to work. :eek:

Are those 64cc chambers? I know the 882's are 76cc chambered so you are getting a bump in compression also. Each point in compression raise is supposed to be around a 4% horsepower increase I believe.

Quick update, slowly been getting things installed...when the wife lets me. :D

Got everything buttoned up, ran through a few heat cycles and re-torqued everything. Went through a few sets of header gaskets trying a fix an exhaust leak. Finally found that I need a set of round port Fel-pro gaskets to go along with my longtubes, no more exhaust leaks.

Started tuning on the car with the new 670 Holley, I have a wideband AFR sensor. Found the carb was jetted lean on the primary side, increased jets 4 sizes and took care of the lean condition. Still tweaking on the tune, will play with timing next.

Looking good and should be running a lot better for you.

I always check my header gaskets against the header and the head before installation. I always use FelPro as well.

Now get out there and burn some rubber.

Part throttle cruising I was running 15-16 AFR. :eek: Once the secondaries kicked, it richened up to 12-13 AFR. Idle was fine at 13-14 AFR. Honestly, I probably need to jet back down to size 68, which is 3 sizes over stock.

It's not very surprising at all, considering I've heard that the Street Avengers are lean from factory.

Jetting...15-16 is not too lean at part throttle. If the car exhibits driveability issues (surging, etc) then yes too lean. But if smooth-go for the fuel mileage.

EFI: most will encourage AFR of 15+. Leaner the better if engine tolerates it at idle/part throttle...otherwise wastes fuel.

I went from 041 heads to AFR 210's...huge difference-big smile on my face!

Car drove like ish at 15-16+ AFR, lean backfiring and all. I've tuned on EFI cars and they love 14-15 AFR, and didn't experience the driveability issues as you transitioned from part throttle to acceleration. Carbs seem to require a slightly richer tune to allow the same driveability. It seems to do best around the 13-14 range, of course time will tell. Also, weather has an impact as well. I may indeed have to jet down come next summer.

Hey guys, decided to drive the car today up to Budd's Creek for the Nostalgia Drags event. Car drove great for the 300 mile round trip. :)

I went ahead and ran the car for some Test & Tune while I was up there. On 225/15 BFG Radials the car went 13.11 @ 102.5 mph with 1.98 60ft time. I plan on adding some MT Drag radials so I don't have to worry about blowing the tires. Also plan on adding 2-4 degrees of timing and stepping down a jet size on primary. I'm sure the car has a mid-12 second potential with some tweaking.

Either way, it was a good day.
