Many Many questions, pistons, CR, injectors etc...
This seemed like the best place to put this so if it needs to be moved no big deal
First of all car will be a 383 stroker motor, more than likely TF heads, Ive heard good things about them. And will be getting a supercharger for it, probably last, but will probably run no more than 14-15 psi ideally
I have SRP -31cc pistons on eagle h-beam 5.7 rods. It doesnt look like there is much room from the top of the piston to the first ring, should I be concerned about this?
How can I determine what my SCR will be after all is done with a stock 58cc LT1 head (it is 58cc I believe) Just using 58cc as a reference, I know the TF have 64cc.
I have injectors I got for free from a friend but he doesnt know what size they are. They are ford injectors and there are a couple different sets of numbers on them. Need to know how to find out size.
And finally, yes I feel stupid but what is the difference between a main bolt and main stud. And can I just go with 2 bolt studs(heard much stronger than bolts but again confused about the difference)
Thanks in advance!

Re: Many Many questions, pistons, CR, injectors etc...
so 8.88 or so CR with LT1 numbers you list and 8.43 with the 64CC.
Pretty low for just 14-15 PSI. Lots of room for more boost.
I would not a THING till I knew what the injecters were and had them cleaned and tested.
Check them out here Stan Wiess's Injecter tables
Bolts go on after the main caps with the threaded end secured to the nut end. Stud's screw into the block before hand and the nut section is seperate
To look at them you would easly see what is what

No one else has any insight?

Re: Many Many questions, pistons, CR, injectors etc...
Easiest way is to go to the top of the threads on advanced tech, go to the calculations thread which has a compression ratio calculator. Make sure you put the piston dish in as a + number not a - since that will make it think it's a dome piston. Gasket height is normally .041 for a FelPro and it's a good idea to zero deck the block which your machinest will understand.
A 14-15psi motor needs about 8-8.5:1 for compression and a 4 bolt main block is definately needed. Either convert the block or find a rare factory setup. Using main studs is also a very good idea along with head studs on a blown motor.
