carb vs fuel injection
I am thinking of swapping my 347 with 24 lb injectors 70mm tb aluminum heads cobra intake for a 351 w world heads torquer manifold and 750 holley. Which would make more power?
------------------ 88 GT mass air conversion from 90lx, Cobra Intake(ported/polished lower),Edlebrock Heads(ported/polished),24# injectors 70 mm BBK TB, 73mm C&L, 347 SB, Wolverine custom cam, 150 shot Nitrous, BBK 1 3/4 long tubes, BBK off road H pipe, Dynomax cat back, alum driveshaft, Konis,Southside Bars w chromemoly torque boxes,AOD w lentech valve body, B&M MegaShifter, 4.10 with Auburn diff, SVO springs, subs, cross drilled rotors,MSD A6 w ign retard, black magic fan etc. |
well, thats a tough question. without knowing the specs on the 351 its hard to come up with a answer. they will probably make close to the same. if you like what you have keep it. if you plan on doing more then go 351. you can always stroke that to a 408. there are benifits to each and both will go just as fast.

Does the 351 already have the correct bracketry for a mustang? Also remember that you'll have to change the fuel system in your car and you'll need a set of 351 headers. Also, please tell me the other guy is going to give you some money, with your hardware your motor is worth much more. You could sell your stuff and build two motors just like the trade one you describe.

Wow, If he's selling it for $14K then it must have some exotic hardware, You could build a yates headed 408 for that much coin! If it was capable of high 9's in a 98gt then there's not a chance in Hedes that your AOD will hold up.

if the 351 is a 9 sec motor then do it. but remember, theres always a reason someone wants to trade a motor like that for a lesser one.
oh my god! he thinks the carb will be superior? using holleys to go 8's? he must be crazy! thats not possible from what im told. hahahaha. sorry, just had to do it. im being told in a post now that carbs are the absolute worst. by a knuckle head. you want a laugh and some knowledge, look at the post tossing the efi |

Regarding carbs vs fuel injection, a rule of thumb is that you make more hp with a carb, but more torque with injection. Just a rule of thumb, though. It depends on a lot of things. ------------------ Russ L '91 LX Procharger, 3 row intercooler, extrude honed Cobra intake, Mac full Length Headers, 30# inj., 73mm C&L, 75mm tb, E303 cam, 289 rods, ported E7 heads, MSD, T-Rex w/255 lph Walbro, 5 lug conversion, Cobra R wheels, 3.27 gears and Moser Axles. |
