Re: What's a good CDI box value these days?

I tried a neat (in theory) Mallory box on a Toyota 22re- the Toyota coil fed the Mallory directly (if I remember right) when it worked...it was noticeably peppier- but that was 50% of the time.

Is the ford TFI and equivalent to the hei coil or better?

I've never had an oem coil fail- however I have had an msd blaster e-core fail.

Re: What's a good CDI box value these days?

I'm running good Crane NOS fire wires with NGK Rutherum gapped to 0.040- Napa down the road has the IC-12 in stock, seems to be a well regarded coil, we don't have O'rielly here. I can only read what I read- on one hand 0.3-0.5 is ideal for HEI oil canisters, then the IC-12 or O'rielly MasterPro XXX...

Re: What's a good CDI box value these days?

NOS oem distributor, NOS 369 GM module, some oem coil I pulled off the pile I collected. I avoid anything with an 'china' identifier. System isn't runing 'bad', was looking for an enhancement with reliability. Since the module seems to be competent with anything out there- is an oil filled coil and ...

Re: What's a good CDI box value these days?

I almost laughed in an email to DUI- they want 'economy shipping' $110usd to ship coil and module to Canada- not likely. Don't want to start a new thread...... - box is out for cdi, considering age of small cap hei, dizzy is new- what are the good parts to wake it up? Or is it a case of it works til...

Loosely based 89 TBI: - EBL/7747- port mod - 385cid, AFR heads - FIRST TPI - bank to bank fire - small cap hei, 369 module, oe coil, crane wires. Never had a reliability problem with GM stuff- whether it's running as-new I don't know, MSD/Accel- I have had issues. What is a "FIRST TPI" "loosely bas...

Re: Edelbrock E-CNC 185 Heads

Still valve guide issues...
Years ago I was looking at various vortec heads (Etec 170/200) and settled on the AFR version for a bolt on- even then complaints about grease used as lube prevented oil from getting in and tight guides. I was willing to pay up front and not have to tune them up.

Re: What's a good CDI box value these days?

Stalled plan to convert to LS 0411 24X ecu. Have everything but the cash;( Had a timing issue where the new 24X timing cover doesn't support setting base timing so I had to reinstall old GM cover with tab. Truck is sporting a built 700R and if going 0411- might as well take advantage of the box and ...

Re: What's a good CDI box value these days?

Eventually moving towards 24X, just the cash for a built 4L60E is in the way- have everything else....in the meantime. Good wires, better GM module (last two aftermarket modules shut me down), oe coil, NGK plugs. BTW I've have cdi in the past- works great.....when it's working, I thought by now ther...

What's a good CDI box value these days?

Not really a msd fan, I do like the old Crane HI6 but they cannot be repaired so buying a used one is iffy- been burnt once already. The new generation (FAST?) is a little overpriced for me. App is 89 TBI, looking for better starting not miracles. https://www.jegs.com/i/Intellitronix/556/150DL/10002...

I know you have them- but why not move forward 40 years, that's where the power is, modern heads and cam.
