Lets see it already...

 

what do you mean? What would you guys use for oil I'm told it has to be at least 14% DHHP real oil I use to put Valvoline VR1, but the builder said it doesn't have enough DHHP

 

Post some pictures of your engine and the EFI unit. Is your builder suggesting herbal health products for your engine or is he trying to say that VR1 doesn't have enough ZDDP? VR1 is a top rated oil for flat tappet engines and has an excellent friction package.

 

Here's 3 I hope. They make it

 

Try again

 

Sorry for the post put it only taking 1 at a time
Yes he said VR1 doesn't contain enough he mention classic car oil

 

I spy an hei. Probably needs a bunch more timing

 

Looks awesome. Did you advance your timing?

 

I'm going to do it today I'll try 12?
To see how she's acts I'll get back to you maybe it will stop the popping

 

Popping?

 

Yes Eric some times when I back off the gas it make a popping noise like backfire through exhaust , I'm going to change some of the setting on the atomic Efi ,I doesn't ping so that's good

 

Nice! Ive been thinking TBI for a while on a 455. Popping on decel is rich fuel, or oxygen getting into the exhaust via a leak or both. Is this EFI-TBI a closed or open loop system? Popping at idle is too much timing or a vac leak or both. Is that HEI a new unit or was it pulled from a smog era engine?

 

Old unit but Inside news when the 6A MSD Box came
