Long time reader first time posting! Noob here from Bedford Indiana looking for some opinions. I'm building a 418 stroker for my 87, I have the 69 351 windsor block, c-3 nascar yates heads and intake ported to the max on both. I want to be able to drive it on the street, but yet be fast enough to out run most at the track, and run on pump gas. Inverted pistons to keep compression down? I am thinking my heads are around 50 cc's with 2.150 x 160's. I have the turbo coupe t-5 with 8.8 and 411's. Opinions greatly appreciated! Here is the heads and intake,

So are you just wondering about compression? N/A motor?


Static compression isn't as critical if you have the proper camshaft. You would be money well spent on a custom cam.

Yes and carb size, I also need to know what rockers to run on the heads, 1.6's, and what kind of horse power am I looking at?

Any idea what those heads flow? I don't know much about them.

I can't remember what the guy said about flow. They are ported to the max and when you look down into the intake, its completely open. I forgot to mention,, all this is going on or in a 1969 351 windsor.

I figured this,,, so should I go with c-4 or c-6 or glide?

[69fastback]

No glide if you're driving on the street. A C4 can be built plenty strong and weighs considerably less than a C6, so I'd say C4.

To answer anything else, you really need to know what the heads flow. If you want the best of track times, and drivability, the best way to go is to get a custom cam from a reputable place, and then call some place like Pro-Systems and get a custom carb. You're probably going to be looking in the 850 CFM range for the carb.

Here is a pic of the heads,

you either need an adapter or run a 4500 carb(dominator) Dominators can be a pain to get to run like a normal car on the street. More of the wide open or idle carb. They make adapters for this, 4500 to 4150 carb flanges

where did you come about these parts too?

I bought the car, traded 3 guns for the heads and intake,, and bought the c-9 block all off of craigs list this last month.
