Thedrue, I owe you an apology. You were right about me being way off on the weights of the lifters. The weights mentioned
earlier are for LS lifters.
So, to be more precise I went to the local auto parts store and weighted one to compare.
60 Degree roller lifter .842
.904 Solid lifter (couldn't find a .842 to weight)
9
So, I still save over 1/2 pound, 11 ounces to be exact.

There are a LOT of those on the market, including ones with the roller riding on pressurized oil instead of needle bearings, making them immune to bearing failure with stiff springs and high ramp rates. |
|
The best ones I've found are 118g and 119g for $600 a set. Still too heavy.
If I replace the ones I have now for a set of these I found I'll be addin almost one pound! 15.24oz to be precise.

I use the best oil for breaking it in and then I use triple esther real synthetic oil after.

That makes more sense! It is a weight penalty for sure, just not nearly as bad.
The v8 lifters may be able to be made to work and would open up so many options for performance parts but there are definitely some issues. The first is the 60degree alignment plates would have to be shimmed or extended to accommodate the taller lifter. That would probably cause interference with the intake and I don't think that is a good option. The other idea I had was to use the cross bar lifters, but the 60degree has closer lifter spacing so they would have to be custom for the v6. I'm still not sure there is enough room for that though.
Such is the life of those of us still hotrodding the 60degree architecture. Have to get really creative since there are very few performance options out there!

Yes Thedrew, I'll stick with the good ol' solid flat tappet. It has always worked for me.

I'm looking into it now. I have to drive 50 miles to get e85. The one thing I don't like about pump e85 is that is never the same.
I think in my case I'll get it by the 5gal pail at my raceshop store. It's always 85% guaranteed and has other enhancers also.

I'm lucky that there's a pump that sells it about 15 minutes away in the same town as the track. 
Does your ECU support a fuel sensor? That could solve that issue with the variation in fuel...
Me, I'm just hoping that pump is consistent. [This message has been edited by lou_dias (edited 04-29-2019).]

I believe you upped your injector's size? What's your AFR's now?
I ordered a set of injectors to do the E85 switch

Since I was using Ford injectors to begin with, they still flowed enough for me to run too rich.
I was lean increasing the BPW by 35% as a base. Settled close to 40% BPW increase overall.
I think my BPW is ~ 82ms ... Didn't have to change anything much other than that.
