Am I knocking on deaths door?

Well, some have blown stock boost trucks. But most 4# trucks are pretty reliable if the tune is good. Octane is correct. And nothing mechanical causes issues.

I beet on my stock block HD for years over 500 hp and around 550 TQ. I upgraded to built long block and still have my running stock long block on engine stand in my shed. All your mods look to be the right pieces to have lots of fun with almost the same list of stuff except I had a 2.3 KB

My cobra has a whipple I want to kenne bell my lightning some day but build a short block myself.

Run it hard don’t be scared. That’s a good FUN setup you got there.

That is an incredibly mild build. The sct2600 and injectors are overkill.

Send it and send it hard.

Looks to me your in the good area.... 😎

No they aren't.

A 2600 is needed for anything more than a 4lb lower.

Any truck with a 6lb lower, or a 4lb and port should have a bigger maf.

The pumps are overkill but not hurting anything.


Op I ran a similar setup on a stock fuel system for years.

Make sure the fuel is good and run it.

I do not consider Maf/pumps/injectors overkill at all. Some do get away with less, but I like the peace of mind and would always recommend upgrades if budget allows. If budget does not allow, I would not recommend beating on the truck...

He has a 4lb lower and a ported eaton. Pumps, 2600maf, and injectors are certainly overkill for that setup, but a good foundation to step up.

Even w a 6lb lower, stock injectors and pumps are usually adequate...with a ba2400.

Except a ba2400 is only available used and only when you can find one. So the 2600 is the preferred maf now.

Depending on age, pumps and injectors when knocking on 450hp is also a preferred method especially when longevity is key.

I would've gone for some 255's but it's not my truck.

I made 425/560 for years with a ported blower and a 5lb lower with a ba2600 and stock fuel. I am well aware of the OEM limits in these trucks.

You are correct Dusten. I didnt pay attention to the hp numbers. 439hp w a 4lb lower and ported eaton is a bit of an anomaly.

OP...who is tuning your truck?

Nice #'s OP!

I think you have a pretty smart little mod list. That's one nice thing about going from a Terminator to a L is you have a good, general knowledge on the gist of what you need to do. There are obvious differences like the Cobra using a returnless fuel system, etc but you enter with a pretty good idea on how to mod a blown Ford from that era.

I didn't even know they still made 60's. You always hear about ID 1xxx whatever injectors nowadays. (I don't keep up well with this stuff anymore) 60's were good injectors. When they first came out with 80's I traded some 60's I had at the time for some new 80's, and I wish I hadn't.
