hello, everyone thanks for all the help in the past , I have been trying to decide what kind of engine up grades to do to the mav. I have the 302 c4 but I would like to have a little more power does anyone have any info on how to build a 302 Boss? This maybe a bad idea but just looking at some of the opitions Anyone have any ideas to help me out. I know that there are high $ engines out there but I'm on a budget so the big stuff is out of the question Thanks
A Boss 302 is quite a different animal than the standard 302. The standard 302 is a great motor and can be built to run very quick. My first Maverick was an I6 with a C-4 that I dropped a standard 302 in. I just freshened it up with new rings and bearings but put all the internals back in, even the stock camshaft. Then I just bolted on an Edelbrock aluminum intake ( Torker 289 model ), headers, 4.11 gears, and a 600cfm vacuum secondary Holley 4 barrel carb. There are alot of different opinions on what the best intake would be, so I'm sure others will chime in. But I'll tell you, that was one quick street car. Eventually I turned it into strictly a drag car and got it running mid 13's with the same combination by fine tuning, removing weight, changing carbs etc...
wait so minus like the removin wieght carbs and stuff.. u got mid 13s with a basically stock 302? not at all doubting, im new to the engine side of things, just impressed how many horses does it have like that stock
For a 1970 stock 302 motor, Ford rated them at 210 horsepower. To propel a 2700 pound car down the 1/4 mile in mid 13's would require approx 250 to 260 horsepower. That sounds about right with the bolt ons that I did to my motor. Plus add slicks, steeper gears with a locking differential, functional hood scoop with cold air intake setup, fine tuning etc...yes it is possible. And best of all, it was super reliable. Never had any problems and ran it for years that way without touching the motor.
you said with a functional hood scoop ram air ? what kind of setup did you use for that? did you do any head work?
Just made sure the whole I cut in the hood was directly over the carb before mounting the scoop. Then I just took the base of a large aftermarket air cleaner ( the kind that has relatively no lip ), hammered down what lip there was so that is was flat. Then just glued down two rows of about 1 1/2 inch thick foam rings. When you place the base on the carb and close the hood, the foam make a nice tight seal to the underside of the hood. That allows all the air coming in the sccop to pass directly into the carb opening. Makes a big difference in performance. No head work was done to the heads. Just a good 3 angle valve job.
The words Boss and budget do not belong in the same post. As Gene points out, a properly configured 302 will have plenty of usable power in the rpm range you will spend most of your time in. Boss motors don't make much power below 4000 rpm. The 302 is much cheaper to build, and it's not difficult to get 300-350 hp. And then there's nitrious, turbos, SC...
Getting 13's in a good running stock 302 can be done , as long as you are willing to give up somethings
almost forgot I ran 12's with a Torker II intake which is a worthless, no good for nothing POS.....just ask around here
wow, lots of replys, i havnt been able to check it this past day cuz well power to the city went out, but thats all good to hear, eventually i plan to do a 302 swap myself, and i want a really nice reliable daily driver that wont cost a ton, looks like i wont have to mod the car too much to be able to have a little fun with it too
sounds like the boss thing is out of the question, I guess I will use the 302 thats in the mav. 330 hp? how to keep it a street able driver? I like the sound of a functional ram air system but dont wont to cut the hood. Thanks
It can still be done without cutting the hood. Try doing some searches on this forum. You might find something on it.
not sure but......... I seem to remember something about taking a 351 block, and putting 289 crank and rods with 351 pistons to make an imitation Boss. I could be way off, but correct me if I'm wrong! I might be thinking of the 283/327 combo that the Bowtie clan used to make a 302.
