Nothcing pistons... How to?

TonyIzCool1 · #1 07-30-2003, 12:04 AM

I want to put on my 302 a pair of edelbrock victor jr. cylinder heads but it says that the pistons have to be notched for clearence. Can you guys help me out explain like how to do that and also if I put that on my 302 engine would i later be able to put the heads on a 351w if i wanted to...Because I wanted to improve my performance greatly but not have to buy parts twice....Thanks All in Advance

First off you are aware Vic Jr are way way too big for a 302 unless you going to run a ton of boost.

Also most people who build a motor that needs Vic Jrs are building some type of stroker motor so they just buy new pistons to work with those heads.

Yes you can use the Vic Jr on a 302 or 351W, they are designed for a 351W so they use a 1/2" head bolt. To use on a 302 use ARP 7/16" head bolts with stepped washer kit.

I can explian to you how to properly notch pistons but unless you have maching equipment its pointless cause you will not be able to do it correctly. So you would be better of just buying new pistons and installing them.

Not to mention, that in order to properly "notch" pistons, you will need to disassemble the block and remove the pistons. It would be better off left to a mechanist to do the work of notching or fly cutting pistons. Have you looked into AFR heads, they flow very well and would make decent power on the 302.

yea my plan is to build a 427 stroked 351w so i was trying to improve on my engine now with the stuff i was going to build that engine with....Maybe I will just wait to get it till I start building my engine,

Where might be the best deal to get a short block 427 stroked windsor?
What are you guys oppinions on this?

sounds real nice to me, I want to stroke mine too. You'll have a beast of a stang, what body type is your vehicle?

To start your search on the engine, i'd begin with the engine factory.
This is a link to their ford section http://www.fordcobraengines.com/

If i was going to do what you are doing i'd just buy stuff with only the 351/427 in mind, and if it could bolt onto the 302 then bonus, but otherwise i wouldn't preoccupy myself with such compatibility considerations.

Stroked 427 Windsor... Your going to make this a Trailer Queen right?

Tony,

What do you want out of your car?

TonyIzCool1 · #8 08-01-2003, 11:51 AM

what do i want out of my car, Hmm..... about 450-500 rear wheel horses, I want it to have plenty of power and if my friend with his firebird challenges me then Sianora for him.... So if you know how i can build a Small block with that much power to the wheels and it is a better and easyier please let me know....Bigdan it is a 70 convertible, GtStang remember the saying no replacement for displacement.

Just remember that HP is easily made with combinations. Take my combo, upgrade the fuel system and slap on a supercharger and you will be close to the HP levels your looking for. Just dropping a stock big block under the hood or slapping on high cfm heads won't do much for you. Ask GTStang about his stroked 351 combo, guarantied he has upgraded quite a bit in that motor to achieve the HP levels he now has. The easiest was to gain HP is modifying the stock 302, they can make decent power without sacrificing street-ability, plus there is an abundance of aftermarket for the 302 which makes it extremely easy to modify.

well how much do you suppose a strocked 351 could produce? It seems to me that his hp and torque aspirations could be met very easily with little aftermarket improvement.

GTStang · #11 08-01-2003, 01:02 PM

Here is the only thing about a 427 stroker Im commenting on. That combo is really pushing the physical limits of that block. It is really mostly used by full on race cars. They do not expect to get 100.000 miles out of the motor. Thet are happy if it last one season. Most who go that route also start with a fresh FMS 351W block cause its the only chance you have to make it last. If you really want a stroked windsor go 393 or 408 much safer.
For the HP levels you want you dont need all those cubes. You can use a 302 blower combo and get it. If you want NA then stroked windsor would be good also. Give it some more thought and ever one here will help you out.

Hi-Flow.... This weekend Worcester Burn-outs. Im gonna give my new axles all they can handles come check it out.

SkylineUSA · #12 08-01-2003, 02:20 PM

Tony,

Look at my sig, there are not too many cars that will have that much HP out there. Its a simple 302 with an S-Trim, my heads are not the best, so there is big room for improvment there.

GTStang,

What do know about the Cobra 351w upper and lower used for a stroker? Would that intake be better suited for a 357? That is the intake I have in my garage right now, with my 20 over 69 block.

Who did you go through to get yours? Or did you piece your together? I want something that is going to be able to hold 650hp to the ground

I was told go with a scat 393, but I have not heard if the combo would be conducive with the cobra intake. Thanks for any help.

TonyIzCool1 · #13 08-01-2003, 03:22 PM

ok so you guys think having my 302 and puting like maybe the Edelbrock Rpm heads and Rpm Manofold with a street demon 650-750 cfm carb and posibly a blower (The Centrifical kind) would it be better for reaching my desired power? Any suggestions or parts to use instead of these....O yea thank you so much for the help

SkylineUSA · #14 08-01-2003, 03:56 PM

Doing a carb with a Centri Supercharger would be a pain in the butt. Your better off the a roots style.

Now if you go EFI, Cenri Supercharger would be fine.

Are you keeping the carb, no matter what?

TonyIzCool1 · #15 08-01-2003, 04:11 PM

well I would like to keep the carb...And i would like all the stuff under the hood...I would love to put the roots type on it that would be awesome sounding but I was reading and saw that if the carb was not perfectly tuned for it, it could like explode or something...maybe you guys can explain it to me alittle better.
