ok so i am going to be pulling out my motor shortly and rebuilding it i have a couple of questions before i get into this project
its an 87 gt factory unmolested H pipe and 40 series dumps with a pro -motion T5 bbk pullies couple other things need a buncha stuff Fuel stuff intake stuff rockers back to the point

ok so im in the process of tearin down my 302 and im about to pull it out of the car so i need to know if im going to need .10 or .20 bearings for my crank i havent got a micrometer and its a factory crank and ect .. i believe it was rebuilt once before i bought the car it feels strong but im going with custom single turbo setup and i want to make sure its not going to fly apart when the boost starts to go up ive begun collecting parts ive got my ford racing fel-pro gasket set and the next things im lookin for are bearings "crank -n-cam" i think the ones im lookin for are H series clevite i need suggestions on rings and what brand girdles are the best i hear FPS makes good ones ..
i got everything to do my mass air setup i need a good cam for boost i think the B or F 303 are good candidates its more then likely going to be a weekend warrior / work transportation lookin to make roughly 350 - 450 hp i dont have alot of cash to upgrade interns and i know theyll hold up well below 500 having block tanked and need a good set of gt40heads /intake setup if you guys got any advice for me id appreciate it any thing helps im not new to rebuilds just not a pro kinda not sure what parts to start collecting
thnx
btw this will all be happening within the next 2 or 3 months so please
criticize me tell me your experiences say im dumb what ever you need i just want suggestions !
later

 

What you really need to do is send the block and crank off to the machine shop. They will be your best bet on telling what you need, They could also offer to balance your assembly for an additonal 200.00, usually the going rate. However, you might be stepping into a whole new world, it might need a bore, and then when you bore it, you will hot tank it, then might as well get it demagged, line and plate honed, and all the goodies, then 500.00 later, only on the block, then you will need new slugs. It just depends. If you plan to go low dollar, like what you seem to be pointing at, just a rering, and new bearings, take your old ones out and measure, but personally, I would have the crank checked by a good shop. Have them polish it and chamfer the oil passages. And they will tell you waht bearings you need.

 

And the F Cam, you will need to upgrade your springs, Even on a set of GT40 heads, you will still need new springs. You going turbo, why not get a custom grind?

 

was thinkin about doin that couldnt quite decide and yes i have a set of springs rated for .500 lift

 

yes i planned to have the block tanked and get the assembly balanced ... does the demagg do anything special? my engine setup im lookin about 2000-2500 turn key which we all know means about 3500 lol "unforseen items/expenses"
then i have a brand new holset t4 and a guy for custom piping i just need to start collecting fuel system parts .... what LB inject should i run with roughly 8-12psi 73 mm tb? or 80 bigger isnt always better anyone with combo ideas hit me back
more advice is appreciated thanks for your replies rep given

 

Personally, I would use 36's minimum. But of course if you can find them, then go with 42's. Your Tb, should probably be about 70-75 mm, and possibly at least a 76mm MAF, I personally have an 85mm tuner MAF.

 

I wouldnt worry about what bearings to get yet untill you take the motor apart and check everything out. Even though the motor has been rebuilt before doesnt mean that the crank has been polished. It still may use the stock size bearings.

 

F cam and turbo = good power, good cam for turbo.

I'd get w/TrikkyBitch in ref. to your build. She's already gone the 302 w/turbo route.

 

At that level of power a stock HO cam would be my choice. What heads are you going to use? You can reach your goal with E-7's but consider head studs. Problem with Ford iron heads is that the decks tend to lift and allow the gasket to push out above a certain boost limit. After market heads have thicker decks.
Has your car been converted to Mass Air?

 

Oops, just read your post again and see that you are converting to mass air. I would track down some 42lb injectors, a matching MAF meter (think Lightning MAF), and adjustable fuel pressure regulator. Upgrade your stock pump to a 255 lph and really think about an external 255 pusher pump like a T-rex. Then have it tuned with a chip.
If your engine is not smoking and on it's last leg why rebuild? Seems like your weak link will be the iron head lifting and blowing a HG then the block.
What size turbo are you going to use?
