1 3/4 is fine for stock small port heads and the type of build your doing. Your not going to pull any kind of effective rpm with the stock intake anyway.

Plus on a application like a truck your looking for lower end power 1500-3000 rpm not 6000-7500...

Small headers are fine and in alot (Most) of cases better for street applications.

Don't get caught up in the bigger is better thing.

I'm looking at some early style C8,C9,Dove heads doing my port work with the stock valves, Thanks Mr Hobbs.
Keeping the iron 4 barell dual plane manifold, with some port work.
Running a holley 750 carb.
New rod and main bearings in the shortblock
Building some 1 3/4 in shorty or mid length headders.
Lunati cams, a couple to choose from, here is the one I had in mind...

ADV. 276/286
@.050 247/256
106 LSA 100 ICL
LIFT .630/.637

I am guessing my compression should be around 9.5:1 but all in all I think this should be a fun modded stock style motor.

Thats to much cam....... Get down in the 230's on the intake. I also assume your not expecting to run stock rockers with that kind of lift. Look at Lunati 61603.

X2! I have a DOVE-C headed 514 unported and the only thing I think is helping it make decent power is the Lunati .568-.580 solid flat tappet. Any thing bigger would just be mismatched to the combo.
