other is intake lift 0.608", exhaust lift is 0.608", adv. intake duration is 304 degrees, adv. exhaust duration is 314 degrees, grind# xfi 248hr-14

Project is a 435 stroker, if there is better let me know who it is made by.
this is my first hotrod motor so i am asking alot of questions. My dad always told me if ur going to do something do it right the first time!!!!!

You've posted a few questions in the last several days. Suppose we get to know you and what it is you want to do with this motor. If you would give us some information about yourself and the intended purpose, we could sure do a better job of advising you.

Is this motor going into the Mustang? Will the motor have to pass emissions? What kind of trans will you use? Will this be a daily driver or a Saturday Night Special that hardly ever gets driven normally. Will you drag race with the car? Street drags or drag strip?

In order to help you with a cam, we ABSOLUTELY MUST KNOW THE STATIC COMPRESSION RATIO OF THE MOTOR. If you don't know, then please say you don't know and we'll try to help you figure it out. Is this motor together yet or what. Is this just something you are sorting out in your mind right now and haven't bought any parts yet. If that is the case, PLEASE SAY SO. We'll still help you. All of us have daydreamed from time to time and put combinations together in our heads and that's o.k.

It is going in a 95 mustang for strip but i want to still run around my little podunk town on cruise night and be safe but majority is for drag. Transmission is going to be a c6 ssmonster (auto) but as far as the stuff on the motor i don't know squat. so all the help on what i need to do to make this 435 stroker run will be greatly appreciated. I live in Indiana so where i live.. they do not do emission testing so no emmissions.

i am sorting out in my head before i strat buying parts

O.K., let's get started. Will this motor be required to use pump gas?

i would like to keep it pump gas

carb?, throttle body?, tuned OEM EFI?, aftermarket injection? (whose)

well i would like to use holley carb with electric fuel pump with regulators

O.K. Before we can size the carb, we'll need to know the maximum rpm's the motor will see. Is this gonna be a no-holds barred effort that will cost $15000 to $25000?

yeah no holds barred

Well, we could get into a Callies crank, Carillo rods, etc., etc., but anyone able to afford some of that stuff would have an engine builder buyin' the parts. So, let's keep it to where anyone reading here could build the motor just by missing 10-12 months worth of house payments.

Speed-O-Motive has an affordable 435 kit featuring steel crank and rods and forged pistons.

Your job is to contact them via email and ask the rpm limit of the reciprocating assembly that is furnished with the 435 kit. Also ask if we should be using a stock or an aftermarket block to start with. Report back here.

Ok i sent them a email should hear back tommorrow (Monday)

Due to the amount of material we need to remove from the cylinders, we recommend an aftermarket block such as DART or WORLD. Rev limit would be determined by your valve train setup (rev kit, etc.), however we do not recommend going higher than 6,500 without a rev kit.

Good job Eric. O.K., we have the reciprocating assembly nailed down. I'm all for limiting the revs to 6,500 because then we can use a hydraulic roller cam. Now, let's choose a block.

Here's the World Product Ford Man O' War block. It can be had in several different deck heights.

And here's the Dart product. We'll have to discuss these later. I have an invitation to dinner.
