Best stock-ish fuel management for a 2.8L stroker?

LOL.



M20 is not a pushrod motor ! Your valve clearances would stay the same even if your head was on the workbench.

In "theory" that sounds very logical and but not always the case. I thought the same until I experienced the change in gap myself.

I've been running the chip from sssquid for only a day now and I'm more than pleased with it. Car is very easy going in low rpm to save mpgs but once I get on it the car takes off. Made a huge difference from stock tune of course and idles a lot smoother. Good customer service and good product. Comes in a cool little package too haha. Would recommend it to anyone and for the price it's hard to beat. I would say go for his chip for your 2.8l you won't be disappointed.

I have run the Alpina B3 software in the past with good results.

I don't understand and/or I don't think this is correct.

My experience is that the clearance closes up approximately .005" after installing the head. Couldn't figure out why my idle was so rough.

Just a side note for the build. Adjust the valves after you torque the head down. After you torque it down the head will compress a little and tight in the gap. I didn't and wound up running the car for a few mins with a very tight gap and had I not noticed this probably would have wound up wiping out the cam lobes.

always check the valve clearances after a rebuild and having run it for a while

I'm waiting for my ssquid chip to come in the mail today as I am doing the break in on the same setup right now as the op. I'll let you guys know how it goes.
The car now is kind of sluggish because of the increase in displacement and 272 cam so I've been really easy on it. However you can feel with proper fueling and timing it wants to go. I am very happy with the results so far from my build. I'm dying waiting for the USPS guy to come by haha.

SSSquid, Jesse is super helpful and will do what ever he can.

I have a similar build as you and went with SSSquid. Message him about your build.

i would do a MAF conversion and someone who does custom chips ask this squid man
The AFM hurts a stroker even the M30 one. i had a custom tune M30 AFM setup and a standalone with generic ignition timing made gobs more midrange. replace the OEM airbox at the same time with a well sealed unit and you are well ahead

I'm putting together a 2.8L M20 right now, and I'm looking for a budget-friendly, stock-ish fueling solution. I've heard that the Mark D chips are the good, but I tried to email him to see if he had something for my application, but I never heard back. I've also heard that the M30 AFM and 19# injectors are one way to go, but just curious if others have done something I'm not thinking of.

Here's the specs of the engine:

9.5:1 2.8L bottom end ("i" pistons, decked block, M52B28 crank, 2.7L "e" rods)
Ported and polished head
HD rockers
272 cam

Thanks
