i was wondeering how many cc and what the valve diameter is on a stock set e7te heads for a 5.0 and also what cam i should run with these heads i have an edelbrock performer cam but i was thinking about going with either the ford e303 cam or the f 303 cam i have the heads in the machine shop now and the builder was asking me what cam i was planing on running so no i dont really know what cam to run
ok the heads are from a 91 302 the builder told me that the valvesare 1.78 on the intake and 1.45 on the exhaust but he did not tell me th cc does what i know sound wright
valve sizes are 1.78/1.45 chambers are 64cc (+ or - a couple ccs) As for the roller cams, unless you've got an F4TE roller 351W block, stick with the flat tappet cams. The little boost the roller cams will get you isn't worth the $600+ cost to convert to roller in a non roller block.
i just look d up my cam size its a .496 lift on the int and .520 on the exh the duration is 224 on the int and a 234 on exh does this sound ok to use with the e7te heads

Ought to have one mean lumpy idle. While some say it won't work with stock heads, I say bull. You'll see some gains with it, just not as much as you'd see with better heads. You'll need better valve springs for sure.
the set up i had was the edelbrock performer rpm series i had the heads to go with the kit but i over heatd them and told they were bolth junk from them twisting when they over heated the machine shop said no fixing these heads i also have the intake performer rpm series as well and wanted to know if the cam will work with e7te heads
If i was building a 351W for a 4x4 truck i would find a 351M or a 351C with 2V heads and put the 2V heads on the windsor block to make a clevor engine. A 351W set of heads from 69-77 has 1.84/1.54 valves. newer heads has same as 302 1.78/1.45. A set of 351M or 351C 2V heads has a whopping 2.04/1.68. There is some water passage issues that have to be fixed and a special intake is required but if you looking for power. Adding those heads should boost you around 30 more hp and around 20 more ft torque than a standard set of 69-77 heads with the 1.84/1.54 valves. port and polish them and your hp and torque will just increase more. 351M engines are junk anyway you can pick a set of heads up anywhere. i think they made them from 75-80.
for a heavy rig the motor needs to be built with torque in mind. and to produce that power at low rpms. if you make the motor breath to well it will move the power band up the rpm range. this is counter productive in a heavy rig. works great in a car or anything that weights less then 3800lbs.
do you think i should go down one on the cam to the edelbrock performer cam ist got a the lift is a .448 on the int and a .472 on the exh the duration is a 204 int and a 214 on the exh do you think that cam would be better than the one i have now to run on e7te heads
