extended crank, hard starting

OK, It has been doing this ever since I installed the 1997 180 horse 12v (155k) in my truck. mods include a 100 fuel plate, tightened govenor springs, fuel plate and AFC slid forward, and an h1e/16 hybrid tubo. When I start my truck, and I mean whenever, not under a particular circumstance, I have to pump the pedal while cranking in order to get it started. It only takes one pump, and it fires right up, however, if I dont pump the gas, I can crank for two days and it wont start. Also, when it gets cold out, maybe below 40, it doesn't stay running if I don't keep the RPMs up, and it blows a TON of white smoke. The truck runs perfect otherwise, and has plenty of power. I can tickle 40 lbs of boost on a 0-60 run. It does get considerably worse milage than my VE motor did. I used to get around 20, and now I average 15, If that is any clue.

Nothing is wrong.
The P-pump is based on WWII technology, there is no computer to give it a little fuel when starting.
You can either turn the idle up or get used to giving it a little pedal.
Personally I prefer giving a little pedal.
Think if you flip your sun visor down it even says to give it a little fuel when starting.

I know my 94 had a problem with that. The suction line to the lift pump developed an air leak (you can't / won't see it, it's suction). I think there is also some sort of drain-back check valve somewhere.

And you should not need to "pump" the pedal either. Just 1/4 to 1/2" of pedal travel is all it needs. Please AVOID pumping it and staring the engine off racing up over 1000 rpm right off. It's a tall block, and it takes your oil pump just a second or two to get oil up all the way to the head, especially if it's cold out there. So let it idle at no more than 800 rpm until you have full oil pressure, then gradually increase for a brief warm-up (not very long there either.) Much of engine wear is accomplished at startup, this is why I stress use a little pedal, not too much.
