Budgett time bomb......
Bore .030
deck 9.000
forged ros flat tops or eqivelant{off the shelf}
10 to 1 compression
factory forged or eqivelant crank
crower 5.7 rods or equivelant {6.0 rod if piston allows}
stock reworked pump{casting flaws smoothed ,oil port enlarged and polished}
moroso or eqivelant sump pan
crane 113801 duall pattern cam or eqivelant
good lifters{possibly?rhodes on the intake and regular on the exaust?}
1.6 intake rockers 1.5 exaust{roller tipped stamped}
good pushrods
good timing set{cloyes double roller}
041 or equivelant heads ,home ported for n2o
bronze guides ,screw in studs ,flat milled to reduce combustion chamber to the 10 to 1 spec
vic junior intake ,plate n20 kit
850 cfm carb {properly tuned for application}
factory hei ,with a good module
20 degrees total advance for the n20
32 with out n20 ,all in by 3000 rpm
1 3/4 headers with 18 inch extensions
This will net you about 400 425 hp at 6000 rpm to 6500 n/a
A big n2o hit ,approxamatly enuff n2o to equall about 300 hp gain ,hiting it at about 3000 to 3500 rpm ,then you use a second stage at about 5800 rpm in the 150 to 250 shot of n2o,this should yield about 850 ponies on the second stage hit and about 700 on a single stage n2o system......
I am thinkin a frugal shopper can put this together for about 3500 bucks.
Now after this price comes tranny/rear end /roll cage /slicks .....:LOL:
Come to think of ,theres nothing budgett at all about going fast :CRY:
I mean really ,are you ever going to be satisfied with 350 hp........Why go at it one upgrade at a time ,buying and selling heads and cranks untill you finally build the mega horse engine ,might as well go all out and when it blowes ,you can rest assured you were getting your moneys worth untill it did ...........let the slapstick flaming begin................,but it will work.
Buil;t properly and kept in tune ,this motor was torn down after 80 ,....yes thats right 80 1/4 mile passes on the single stage and was good to go ,other than some bearing wear ,which is a given at this hp level ,in other words nothing out of the norm for high horse n2o motor.
Do not go crazy on the head gaskett either ,it is like a blow off valve ,it blows off ,you put another on,o ring it or use a metal gasket and the piston or head becomes the relief valve.......
