looks like a 4barrel :shrug:

May wanna try in the fox forum. gonna move it for ya

svopaul

I'm not sure what you are looking for....at first glance it looks like a 302 with stud mounted roller tip rockers and it resides in an SN-95 Mustang(probably '94-'95 based on the brackets and alternator unless sourced from another car. The Carb appears as though it might be a dual feed or double pumper Holley the only way to tell exactly what it is would be by the numbers off the carb itself.

Scothew

ah ok I see the sn-95 body now. I noticed it from the wiper cowl below the windshield. I thought it was a fox based car previously, hence the move to teh fox forum.

nice collection SVO. i really want an 86 SVO i love limited ed cars.

chadstang

I WAS TOLD IT WAS A 351 IT HAS SMOKED MANY FOX BODY STANGS BUT DONT KNOW FOR SURE IM NOT CLOSE TO HER FOR MILATARY REASONS THANKS FOR ALL THE GOOD INFO I DO KNOW THAT IT HAS ROLLER ROCKERS AND THE TRANNY SEAMS TO HAVE A BIGGER CASE THANKS AGAIN CHAD MILLER USMC

svopaul

It does not have "roller rockers" it has "roller TIP rockers"....big difference. I can't way for sure without better pics but that intake looks more like a 302 intake than a 351 intake...which is wider than the 302. I would need a better pic to view the width of it.

chadstang

can you explain the diffrence in rockers and what set up is better

svopaul

Those rockers pivot on a fulcrum and have a roller tip that rests on the top of the valve...better than stock but not as good as a full roller which also has needle bearings and roller in place of the friction area where the fulcrum is. Full Roller Rockers offer less friction over the other styles.

hey thanks for the 411 also i was wondering if u can help im having a very bad time with a oil problem im not getting it to the top end and my pressure is running very high can you make anything of this also is it ok to mount a holley fuel pump in the spare tire well

svopaul

If you are not getting oil to the top end of the engine then you really need to check your oil passages for blockage...if the pressure is higher than normal it could show a blockage or other issue...but with high pressure you should definitely be getting oil to the top end unless there is a blockage or problem somewhere. Make sure nothing it clogging the oil feed passages and make sure the head gaskets were installed correctly(not backwards).

I would NEVER mount a fuel pump inside the passenger compartment of the car...mount it underneath the car away from exhaust and use the proper fuel line(braided is better).

chadstang

do i need to strip the motor down to find if there is a block in the system are what would be the best way

svopaul

Not necessarily....the first thing I would do(and it's going to be messy would be to fire the engine without the valve covers on it to see if you are getting oil to the rockers....put towels on your fenders. Or you could remove the distributor and put a drill on the oil pump driveshaft and spin the oil pump to see if you have oil to the top of the valve train.

WELL WE PULLED THE HEAADS THEY WERE IN BAD SHAPE IT IS A 5.0 BUT HAS 289 HEADS CAN ANYONE EXPLAIN WHAT DIFFRENCES THIS WOULD MAKE IS IT BETTER ARE WORSE

bob

What do you plan to do?? If your working on a budget (read no porting or money to spend on aftermarket heads), dont do a dang thing to those 289 castings.

My advice, ditch the old school heads and go rob a V8 explorer. They came with gt40 or gt40p heads, the latter is a bit better, but in most cases you have to get p specific headers.

chadstang

the heads are being ported and polished as we speak but am i starving horse power by having 289 heads

bob

If your having them ported then don't bother looking for a set of GT40 or GT40p heads. The 289 castings will end up flowing about the same after the P&P work.

If you dont mind me asking, how much are you paying to have the port work done??

The reason I ask is, I've been down that road before. I had a set E7TE's P&P'd with bigger valves, converted to adjustable valvetrain ect., Spent about 1200 or 1300 dollars on the heads and I ended up with heads the flowed about the same as a set of Windsor JR's. After a exhaust valve retainer went insurgent I killed the block and heads on that 302. I moved up to a 347 and this time got a set of 185 AFRS for about the same money. Vastly superior cylinder heads for the same price.

I also am having a good little 302 built using Gt40p's No P&P on the heads, just a switch to undercut valvestems and a adjustible valve train. As soon as they are finished I'll see what they flow and I'll post #'s if anybody is interested in what a set of stock Gt40p's flow with thinned valvestems.

chadstang

complete upper rebuild is running me around 1300 thats for a new carb rebuilding porting polishing etc but its a friend of the family he is not charging to much for what he has al ready done

bob

Have you cut into the heads yet?

chadstang

I dont know all of what he has done but i believe the are do back soon
