that is a loaded question. Make sure you know what you are building it for and choose wisely. I like the Hydraulic roller cams for street/strip use. You can go custom from FTI (Ed Curtis) or Anderson Ford Motorsport makes nice cams. you need to know what pistons you will be using to make sure they will clear the valves and gear ratio and intended use of the engine. the AFM N-41 and N-51 Cams make great power and will clear most stock pistons. The N-61 and B-41 cams need Aftermarket pistons.

Agreed. My Comp roller is a 35-518-8 and has 224/232 duration and .555/.565 lift as an example and works great on the street with my set-up. I am running 3.50 gears with 26" tall tires and a 10" 3,500 stall converter in my C4. Personally I'd call Comp Cams and ask them what they have for it. I hear they're now making a new design cam that has four patterns rather than the single or two pattern designs that most cam grinders use today. They also have stroker specific grinds and their "Thumpr" series cams that would also be a huge step up from what you have now. Some well known engine builders here like them.

With a manual trans and that light of a car you can go even bigger without a problem.

It depends on the year of the 351 heads..Look between the pushrod holes on the top side for a date code and a casting number on the bottom side of the heads..The 302 4V heads have great combustion chambers for compression but aren't anything special otherwise..The 351 heads may have bigger valves for better flow but could also have huge combustion chambers and small valves as well..It all depends on the year.

Re: 302 Stroker engine question

OK so the casting code is D0OE so I believe they are 70s is that correct? Which means this is the specs. 60.4cc chambers, 1.84/1.54 valves.

Yes..Check the date code to be sure..The heads would also have pressed in studs and the big diameter spark plugs.

Re: 302 Stroker engine question

Ok another question. I'm getting these heads cleaned and checked for flatness and all that good stuff. I'm assuming the valves and seats will need ground cause some are pretty rusty and I was gonna get new valve springs. So I'm assuming with that I'll have about 300ish into the heads. Is it worth it or should I get some aluminum heads. I'm trying not to put a ton of money into this motor so I don't want anything crazy but I found some aluminum heads on eBay for about 400. So are 351 heads any good compared to the new stuff..

If you are going to use a decent Cam you will need screw in studs. By the time you rebuild your heads with new springs, Guides, Valves and machine work you would be better off with new heads and you will be well over $300. For a budget build you would be better off with some TW 170 heads as they can usually be found under $1200. What camshaft are you going to use as this will determine how good of a spring you need and whether you need screw in studs.

Re: 302 Stroker engine question

I would be very wary of those cheap ebay heads..They are likely pro comps or something similar with very very cheap components in them and possibly very bad castings as well.."If" you can get a good set and install good parts in them you will probably be approaching the price of a good set of name brand heads anyway..If you can clean up the windsor heads for around $300ish and they already have screw in studs that might not be a bad way to go if you aren't after maximum performance..Of course you also need the proper springs for that camshaft or whichever cam you go with.

Well it is possible to use those heads it does require different pistons/rods/intake/headers and some machine work on the heads..Basically you would be building a boss 302..There are much better options out there that will bolt right on to your existing setup.

Re: 302 Stroker engine question

Yeah I just noticed they were Cleveland heads and started looking and seen the whole Clevor thing. I don't know I kind of like the whole Frankenstein engine idea..lol A lot of work but it's different. One thing is I was trying to see if they make boss Pistons .040 over couldn't find anything.
