351

[Pimpdady753]

ok i was woundering if it would be easer to bild a carb engine in stead of a injected, and i need no know like what ill need and what i will need to modify it so it will fin in my 1990 ford mustang gt, right now it has a 302 but im going to be putting the 351 in in, also superchargers what is a good supercharger i could get the ones that sin on top of the intakemanfold, (dont know the exact name) i was think of getting one of those race scoops with the 3 red plates that open and shut, im not a conpleate noob with the fuel injected, but ive never tuched a carb in my life, would it be cheaper to bild the injected engine or the carb, im leaning more tords the carb thanks.

Cheaper to build an injected motor than a 351 with a 6-71 blower on it. There's a bit more than that. You'd have over 1500 bucks in carbs, unless you use a smaller weiand single-carb roots blower, which means a 950 carb, still a 750-900 dollar carburetor. Not to mention if you tune it right, you're looking at well over 500 HP, which throws out a stock block, now you need a 1000 dollar or more block with internals to match. You're talking a lot of money, even if you shop around.

I wouldn't bolt on a roots SC if I didn't even know what it was called.....

Research, bud, research...

Not to push any button SVT but he could get a 750cfm Mighty Demon blower prepped draw thrue carb for $532.99 I think I payed at Jegs. Had to send it back because I was supposed to be getting a blow thrue carb. However the roots blower and the intake needed wouldnt be cheap. Build a motor somewhat like mine if you want lol. Although I'm useing a centrifugal blower and not a roots style. Still 500-600 rwhp on stock block/crank. Just be carefull with your tune. Keep the R's low, the timing down, and the a/f safe.

so what kind of carb would i need i, do plan on putting a new block and forged internals the hole works, i was just wounder wich would be cheaper to bild up a injected witha vortec supercharger or a carb with a root sc. how hard would it be to put a carb in my 1990 mustang fuel injected, like what would i have to get that i dont have in the car right now.

I thought you had money?

[SkylineUSA]

Roots are on all the time, it will suck the gas, plus with the carb even less MPG. But to build the carb is way cheaper, plus you can tune it yourself with an EGT and a wide band.

[SkylineUSA]

You can build a vortech with everything for FI for less than 4k, if you shop around. MAF, injectors, S-Trim, etc.

What intake and heads do you have?

[Pimpdady753]

im bilding a hole new engine i dont know witch heads im going to be getting same with intake and that depends on if i go carb or fuel injected. ic what your saying about the roots charger being on all the time and sucking the gas. like how many miles do you think ill get.

[SkylineUSA]

Carb, lucky to get 14mpg


My Vortech S-Trimed Stang could get 22mpg on the highway.

[Pimpdady753]

how many miles do you think i get now i have a 302 with 137,000 miles on it, with cold air intake flowmaster bbk headers and x pipe, msd 6++ ignition and msd coil, i dont think i get vary much tho i think my engine is messedup or out of tune,

Depends on the history of the motor. Some 5.0's can easily make it over 200k miles, some crap out at under 100k. Currently, my 92 has 140k and it still runs very smooth and strong.

Im going to go carb, is this a good setup, cam the (TFS Stage 2) with the kb dished pistons(unless there is a better kind, any sugestions) with the 58cc head for a 9:1, also the H-Beam Super Racing Rods, with the twisted edge heads, with a 392 block, is this a good setup for the carb engine, and then i will need a carb or duel carbs and intake with the roots blower, i dont care about mpg, so i need some help on witch carb and blower i should get, thanks.

[351wStang]

Holley and Demon both sell draw thru blower prepped carbs for around $500. Thats not a bad price at all. The cam is a pretty good blower cam from what I understand. I'm not a fan of kb pistons. I got my probe pistons for about $450. If your going with H-beam rods the least you can do is forged pistons instead of hypers. What are the flow numbers on the tw heads? The heads really depend on your budget. I bought Edel. Performer RPM heads and wish I had gone with Vic Jr's or TFS Hi-ports. The blower depends on how much power you want. If your set on a specific psi of boost say 10psi then buy a blower that will give you some room to grow. Your gonna be spending a ton of money on the blower, spend a little more and get a blower that will allow you to take it to the next level.

Guess I didn't check before I opened my mouth. Thanks for settin' me straight.....

Draw through suck

They have huge starting issues along with other crap to deal with. Blow through is the only for me.
