Pitching the EFI!

juiceman it's pretty obvious technology scares you. If you really think you can build a cheaper faster carb that will be streetable come back outta the late 70's, dude.

Here's a few combo's for ya.

E303 cam $160
Cobra Intake $399
GT40P heads $400
Pro M 75mm $200
65mm T/B $190
1 1/2" unequals $120
hi flow H $150
2.5" catback $250
155lph $80

$1950 That combo should get her car into the 12's. I would be shocked if you couldn't tune 310hp out of it.

E303 cam $160
TFS TW Heads $900
TFS Street Heat $395
24lb/hr $189
Pro M 77 $400
75mmm T/B $200
1 5/8" equals $150
Hiflow H $150
2.5" $250
190lph $100

$2894 That's good enough to put 400hp down on a 302.

E303 $160
TFS Heads $900
Cobra Intake $399
65mm T/B $190
155lph $85
1 5/8" LT's $250
Hiflow H $130
2.5" $250
AFPR $80

$2444 That combo on S/D should rip off low 12's@115mph or so.

I'm not seeing this $500 mid 12's pass, juiceman? Are you doing this on the stock heads and cam? No fricken way. Even your magical ancient carb needs some other mods to the engine to pull 12's. Course, maybe your the one that needs to lay off the smoke?

What fuel pump? What heads? What intake? What carb? What exhaust? What cam? I'm doing a little number crunching here, but to put together even a 600cfm carb and intake combo will run over $400 just to convert. You think losing the EFI alone will give you 150hp?

My car will run high 13's in it's current form. I get 19-21mpg in town, about 27-29mph hiway. That's with 2.73's. My engine is totally stock, except for a K&N filter, hi flow cats, and hi flow catback.

As far as losing hp and torque with a carb, you're damn right you will, unless it's tuned perfect. On a race engine you could expect to pick up 20hp, but you'll lose low end, and you'll lose streetability. I wouldn't even try the fuel economy route dude. One malfunctioning electric choke, leaking vacuum line, or slightly improper tune will send her soaring into the low teens for city driving.

I've owned 2 carbed 5.0's. Neither one of them got **** for fuel economy. 20mph was a sweet number to pull on the road. Now I get that running in rush hour 1/2 the time.
