Yeah.. but then he needs to swap transmission too. So much for being cheap or easy.
What are toploaders going for used now a days? Versus a set of injectors and an ECM and a custom map?

It will perpetually throw codes for 4x4,
Here's the deal guys.
This isn't a daily driver and I want it to be as quick as I can get it on the first try, but still street driveable.
I think I can get substantially north of 300hp. I am willing to pour some cash into the valvetrain to handle a cam a little better than that, Paul. I guess my question is, how far would you go on camshafts with a MAF set up? Could I get away with part # 35-324-8?
Here's the real deal.. despite what you want out of this motor the heads(and the intake) are going to limit the powerband to about 4500rpm so even the 35-320-8 gives you a lot of room to grow. You should see just about 300 ponies with this combo but add the heads and intake this motor should have(AFR185 and TFS-R intake) and you're bolting on 100hp with no other changes. The 35-324-8 is just a bad mismatch to the current combo which means it'll make less HP and quite a bit less Tq than the more conservative cam I suggested.
I'm going to let a pro do the transmission. I don't know how to put more magic into it.

Didn't figure you would try tearing into it, and would advise against such. Too many special tools, and too easy to mess up. I was more thinking pull it now and take it to a pro, do a cash and carry. Saves the r&r cost.
Yep.. that's what's in my motor.Alright... So you feel confident with running stock lifters, pushrods, rockers, springs, etc with that cam?
yes every little bit helps.If I decide to swap on a new intake down the road, do you think it would gain a little more horsepower?
Yes it'll cause problems, and I've already told you how to get around that.. simply install an adjustable FPR and crank up the pressure a little.It seems like I'll be out on the edge of the 19 lb/hr injectors. Should I swap to 24 pound injectors so the 19 lb injectors don't run near their 100% range, or will that cause me tuning problems?
Unfortunately there is no way around that, if you put the big cam in you'll be stuck driving an underperforming slug that will piss you off because it's so sluggish for what you spent building it. If you step up and get appropriate sized heads and intake for it now you also need larger injectors, a larger fuel pump, a larger MAF meter, and a tuner to make it all cooperate. This "calibrated" MAF meter trick you read about only works at WOT, everywhere else the motor will run like *** because fueling requirements are now completely different than what a stock motor needs. Bottom line is there are no shortcuts, you build to the limit of what 19lb injectors and the stock computer calibrations can handle because the next step is hugh and expensive.What I'm really trying to do here is build this once rather than constantly swapping in parts chasing 10-20 hp at any given time. I don't mind spending a little money to get this right the first time.
