Thanks so much for these responses/ideas.
I thought I had this problem solved w AFR and Timing, but engine temps of 200 still have a problem cranking. I'm running the fans for 3 minutes after engine turn off - the engine temp seems to top out at 209 (on these warm days)
It could be a heat...
This morning was a good.
I gave the idle and cruise a little more gas (idle: 14 to 13.5 AFR. Cruise: 14 to 13 AFR), and ran the car down the road.
The engine ran cooler than it's ever been, it pulled nice and hard - the cooling fan never kicked on. I parked the car at 185 degrees and it...
Hi,
The starter is a (new) Mini. It does crank over fine when engine is cold.
The engine does seem to like timing, but one of the threads I read here suggested too much timing will cause heat/detonation which could give me difficulties w the hot start.
I will put the idle timing back to 15*...
I think my question to the Group is about timing, but AFR seems meaningful in the tune also.
I have a ’71 charger that starts right up and runs well, but when I try to restart the warm engine it’s like I’ve lost my battery – it does that fraction of a crank to compress that 1st cylinder and...
Austin,
Thanks for response and your photo . . . my project was much easier. I bought the car from the original owner 27,000 miles, stored winters. I kept up the storage: 47,000 miles now.
Originally it came w 383, 2BBL, single exhaust, 727 w the shift on column & 1,000 rpm stall, 8 1/4" rear...
I'm new to this Forum - I like it.
There's alot about the Sniper I like too. Mostly I like the adjustability from the Hand Held. There's a 'Prime' enrichment, Coolant temp enrichment, Acceleration enrichment, Load enrichment based off MAP, timing and AFR. It's more expensive than a Carb, but...
Sorry - my bad the hyperspark distributor is SNE 565-305.
Holley Tech told me to use a canister coil. I'm assuming that the coil driver and the MSD box do the same thing.
The car originally came w 727 automatic shift on the steering column - I bought the Tremec and the kit from Silver Sport . . . it came w everything I needed: Transmission, Bell housing, pedal assembly, hydraulic clutch, tunnel and 50 pages of instruction.
Sorry - not sure that helps you.
I really like the Sniper now. Originally I bought an edelbrock carb and I was researching how best to do the tuning when an episode of Garage Squad ( Cristy Lee :) ) bolted on an EFI, and I realized the differences in tuning between EFI and Carb
I'm not going to race/beat on this, but I do...
I wanted to share some thoughts and opinions I had in adding the Sniper EFI to my 71 Charger. At the time, I couldn't find information on some of this setup. I hope this information helps someone to do a better/quicker job than me. Let me know if you have questions/suggestions.
Car: '71...
In '81, when I was 18, I kept running into old timers who wished they kept their first car. Now that I'm an old timer - I'm appreciative of their comments and happy I kept my '71 Charger. This was a 4 year resto-mod.
Numbers:
383 bored and stroked to 413 w comp cam 270 and Holley Sniper EFI w...
