302 valve clearance
 

Im looking at installing an aftermarket camshaft in my truck,its a 1979 Ford 302,thats been rebuilt by Ford (been in storage for LONG time) i added a summit 600cfm 4bbl,pertronix ignitor and shorty headers..aside from that,the motor is bone stock.I have installed a camshaft into a ford 289 years ago,the duration was around 255-260.i dont remember much about the cam specifics,but it wasnt much bigger than stock..this time i want to add a duration of 260-270 but im not sure if thats a good idea,more lift also worries,me..got a rough idea of cam choices that give good power between 1500-2000rpm,And i would like to keep the engine together meaning i dont want to remove the heads and have threaded studs,guides etc...just a cam that adds more than what i had last time,but nothing so big that im putting the valves into the top of a piston.or any other serious issues

You will have no problems with stock valvetrain/pistons with a cam under .465 lift..

im not a big fan of modifying engines,so i get a bit lost when cam numbers start getting thrown around.I was looking at the 268H from comp cams.I definately want to favor the exhaust side because those ford exhaust ports are small

That is a very mild cam. Great for stock type engine.

thank you!

Do you have an opinion on those 'Rhodes' anti-pump valve lifters?...again im not a huge fan of modifying engines..well,a little bit i like but i find if i stray too far from stock..troubles develope.Stocks hard to beat for simply getting into a vehicle,turn the key and go...im not looking to get 6000rpm out of my 302,you take a stock 302 beyond 4000rpm and youre just beating a dead horse.

This may be just right in your case as I have one in my own 302,Ford Racing has dropped their hydraulic cams and only has hydraulic rollers available, the old Ford Motorsports part # M-6250-A-311 is now available as a Summit Cam package Summit Racing SUM-K3600 - Summit Racing® Cam and Lifter Kits - Overview - SummitRacing.com the Edelbrock Performer cam has similar specs the extra exhaust duration is always a plus with stock Ford heads as it helps to overcome the poor flow.This one is a hydraulic copy of the old COBRA cam if you want a more "nasty" sound http://www.summitracing.com/parts/SUM-K3601/ and still have good low end and mid-range.

Not a fan and no need in your application.

Not worth it,I give the Rhoads lifters a thumbs down and the "click-click" can get annoying.

I was thinking about using them,Because as i was cleaning out my dad's 'stash' of oddball parts and pieces that he kept around to use on projects,there is a box of rhodes lifters and they were for his 351w i think.I will trade them for something i can use then.Stock lifters have never given me a problem.Thanks guys
