youll never get 260rwhp out of a 2v using completely stock parts
youd have to cnc port the heads and intake then cut the base circle down on the cam while praying to whatever god you believe in to make that happen
no they arent
Ive dyno'd several hundred 2v's and they are all 195-205 rwhp all day long.
What your saying is impossible and your peers are feeding you lies.
thats a pretty crappy class
a bone stock ls1 puts down over 300 to the wheels
apparently their target is older 302 fords vs older 305 gm's
my all original 2000 lincoln ls with stock manual 5 spd trans would dominate in that class
There probably is no way to get a DOHC engine with only 4.6 liters of displacement to make more torque than HP
Maybe custom grind some tiny cams? Then a custom short runner intake.
You’re going to just have to accept the physics at play here.
So basically, you're looking at the combo that requires the smallest weight. The 4V heads still will be your best bet, as they flow much better. So, looking at factory numbers, you got 305/300 fwhp/tq w/ B heads, 305/320 fwhp/tq Mach 1 trim. Assume 18% driveline kill, you should have 250/246 w/ B Heads, 250/262 03 heads. You're just about at the hp mark, but you need more torque. Long tube headers should give you a good bump, but not necessarily up to 310 rwtq. If you can bump the compression a hair, that will get closer. Then, to make sure you didn't go over on hp, you can advance the overall cam timing. Starting 2V, you have 260/302 fwhp/tq in PI trim. Compared to the Mach1 trim, you already penalized yourself, even on torque. It's a bigger hill to climb at 20 ft-lb deficit using mostly factory bits. Remember, you have a 281 ci engine regardless, trying to make over 360 fwtq.
