hey everyone..new to the forum and looking for some help..
just bought an 87 5.0 with a stock bottom end, f-cam, edelbrock performer intake and aed 650 carb and stock iron heads that have been worked (ported/polished and maybe upgraded valve springs as far as i know).i have 6.800 pushrods and i need to know if this combo will work without any PTV clearance issues and what ratio rocker arm i need to go with..hope this is enough info to get this thing up and running strong
thanks

also forgot to add in that the heads have been shaved 0.030 and i have the shims that go with it..and the stock pistons have the 4 valve reliefs cut in them..bare with me im just gettin into this

[goose-it87]

anyone out there with some helpful info?

You're gonna have to check ptv no one can tell you over the Internet if you're valves are gonna smack you're pistons , there's a sticky on here of how to check it

6.80 pushrods? How did you come up with those? I beleive stock 5.0 pushrods are 6.25.

[goose-it87]

6.800 is stamped on the pushrods. found out the previous owner had tftw 170 heads with 1.7 rockers and the f cam. i got the worked e7te heads from a friend because the tf heads didnt come with the car. now im trying to figure out if the f cam is going to be too much for the e7 heads

I'm willing to bet your valvetrain geometry is all messed up. I'd get a pushrod measuring tool ($8) and measure for correct pushrod length first, before you put some serious wear and tear on that valvetrain.

[goose-it87]

so once i get the correct pushrod length, what about the aggressive f cam and stock heads? (theyve been ported/polished/dual valve springs) combination as far as power goes because im guessing the tftw 170 heads flowed alot better and complimented the cam better than the stock ones will.

[fogged306]

Twisted wedge heads require longer pushrods than stock ones. Those 6.8's will be way too long... As far as using the f cam with stock heads, it's been done plenty of times. It's not a radical cam by any means. It's also not a very good cam either.. Impossible to tell you how well it will work with your heads without flow numbers if they're ported.

[goose-it87]

well im going to stick with the stock ported heads for now for budget reasons. so i guess my next question would be a cam recommendation to get the most out of what i have.
-so would flow testing be the best advice to recommend a cam?
-the car has an aed 650 4 barrel carb, edelbrock performer intake, (bbk?) shorty headers, h-pipe with no cats, flowmasters, c4 trans with 4.10 gears, all msd ignition components. (hope this helps)
