I would have loved to get a 6.2, but I do have to say my 5.3 on e85 is no slouch. Any of the 6.2 guys run a 5.3 on e85? I'm curious as to how close it would be. I do agree, my 5.3 on 87 is a dog, but the e85 really wakes it up.

 

I ran 9.16 @ 75 on E85 full weight bone stock with the bed liner and backflip cover so reasonably close for RC 5.3 vs 6.2 I'm guessing. Wouldnt bet on it for the 1/4 though.

 

I run mine on e85 pretty much at all times. Mine is also tuned and the timing is bumped up about 4 degrees on the e85 table. Izzz nice!!

I ran a 6.2 one night a few months back, it happened to be one of the only times i've had 87 in the truck, it wasn't pretty.

I should be getting headers soon, once I do I should be real close to 6.2 numbers.

 

I hear that, not sure if I wanna race some one with dat Sam Milla tune though lol.

I'll have to keep the offer in mind so I don't forget. I feel like you would pull but a tuned 6.2 with headers may give you a decent run.

 

That would be FUN

 

Its just hard to justify putting much into the 5.3 when the 6.2 flows so much air with those big heads! I mean by the time you do cam and fuel system you could have a 6.2. And my blower fits as do headers so I really do think its the wisest decision by far to change it out instead of mod this. I'll be out of debt in 1 yr so in 2020 I'm doing it if not sooner! It will be true love then.

 

I fully agree man. The heads out of the box stock do 330 cfm. And you're exactly right, I was looking at doing a cam and ported heads. The ported heads would cost me what the 6.2 would (after I sell the 5.3 to make up the difference). Just silly. And if I do cam and heads, I still wont make 6.2 torque.

BTW, I realized on my way home that you have a single cab, yes I know it's in my face in your sig pic but I was just typing away earlier without thinking. Dude you'd kill me even if I got a 6.2.

I'm working on convincing the wife, she isn't up on it much but she knows how bad I want it. One good thing is she doesn't like it if I lose and I got beat bad by a 6.2 Yukon Denali that a buddy owns so that's helping my case and 10 minutes ago she said she was getting me headers for christmas so that's a bonus.

BUT I raced him on 87 octane, right after I wrote that message above I left work and ran into a new escalade on the way home and pulled up to a stop sign beside him and asked if he wanted to run, he said yeah it's a rental! LOL so I'm on e85 today, and 1/4 tank of gas, perfect. I also now have a magnaflow muffler instead of the stock one and had the flapper cut out. I pulled harder on him than the Yukon Denali pulled me so the muffler and flap delete with e85 made a huge difference. With headers I should be closing in on stock 6.2 power and that was a goal of mine.

After I explained to the wife that I can do a 6.2 for 1500 she's on board for the most part, but I have to get her a new car first. No biggie we sold her super clean modded mustang and bought a boat, now it's time to sell the boat so I can swing the new car. After that long *** story, you should still bust my *** if I have a 6.2

Oh and lastly, I told the wife if I do a 6.2 I'm doing a small cam and DOD delete before the motor goes in. If I do a small cam I can keep the timing chain, springs and pushrods and keep the cost down and maybe make another 20-30 hp at the same time. I don't want a big cam, just something to get rid of the DOD lifters mainly. I still want MPG

 

I like your plan and God bless your wife for having your back on everything that's just awesome. Well if and when it ever happens maybe I could just load my truck so they are equal weight. That way it would be a good comparison. All in fun anyway I don't take it that seriously lol. Now, power lifting? Different story! Verrry seriously.

 

 

For sake of convo. My stock truck did 9.0 at 77. With cat back, intake and ecm / tcm tune it went 8.8 at 78 and a 13.8 at 99 in the 1/4.

These trucks come pretty well off from the factory.
