I currently have a mid 80s 302 short block that is ready to be finished. I am looking for a a top end set up that will produce about about 375 hp and im sure that should be pretty easy.

Here is the rotating assembly that has been installed

So as I stand now I am asking for help in choosing my top end parts. I would like to get it all for about $2500 total.

I am not looking for a race engine. Just something I can have fun with. I was thinking about an edelbrock top end kit with rpm heads and an air gap. I think that is the way i am leaning. However, I also need cam, lifters, spider, carb.

Im not looking for a custom ground cam. Im looking for an off the shelf set up that i can put together.

Please send your recommendations. I need this car together and out of the garage.

Thanks

Not a fan of Edelbrock cams. Their off the shelf cam grinds don't impress me. Call Comp Cams' tech support for an off the shelf cam recommendation based on your specific setup and desires. With the proper valvetrain hardware (matched springs are a must), I think you could get away with a pretty aggressive cam. You do need to know if you want/need a flat tappet or a roller cam.

I have a set of Trick Flow Twisted Wedge heads and I really like them. Plenty of valve clearance until you get up into the .540" lift range. That said, Edelbrock Performer RPM's are also supposed to be pretty nice. AFR's flow well, but I've heard a lot about their valvetrain hardware being crap.

 

So it is a roller motor then? I don't see any problem with reusing your stealth (port match it to the heads) and 670 carb. Head choice is an opinion preference thing as most HP parts are. I'm with Starfury and haven't been really impressed with the Eddy 'all in one' kits, they seem to be in the middle on comparison tests. Do a search for head comparisons, there have been plenty of Mustang and hotrod magazine articles you can read. For heads I'd look at TFS Twisted Wedge and AFR 165. I went with the 165's for my stroked 333 to avoid piston issues and over sizing with the 185cc and the flow was best for my RPM range and cam grind.

Here's some great charts to look over for flow comparisons:

As far as cam, plug in all of your car/drivetrain variables and see what top 3 cam grinds are suggested with CompCams free Camquest program, even if you don't buy CC it'll help get the grind you want:

change a few things and see what it does to the grind suggestion. I did this and my engine builder and I came to the same 2 grinds and I chose my preference. Had to be honest with myself that 90% of the time it would be a DD street car and only see 10% track. I was conservative with my cam and went with the XE262, many suggested the 268 (it's habit I guess to always 'go bigger') but I listened to the 268 in a friends 289 and it was too lopey and the vacuum was too low (<15) for my PB and AC, to me.

Not sure why you don't want to go with a custom or semi custom cam, Ed Curtis will set you up for what you have and what you want to do with it. I went with Morrel link bar lifters and Comp pro magnum chromoly rockers to go along with the Ed Curtis cam, heads are Trickflows (170) with a stealth intake and a Holley 4500 from Bigs.

My short block started as a 1990 302HO, I had my shop balance the rotating assembly. Ford did a good job but now it's perfect.

 

Yes it is a roller block.

Jonk, this is a engine for another car, not the one on my sig.

I have decided on the tfs heads

I am going to go with a air gap intake.

I have a set of magnum roller rockers that i am going to use.

I just have to decide on the cam and lifters.I am going to jump on the CC site now.

 

I am leaning toward these heads

Here is the intake

Im leaning toward this carb
http://www.summitracing.com/parts/HLY-0-80670/

I just need to get a cam and lifter choice. I will call a few com companies tomorrow

 

190cc is way too much intake. Also be aware that many of these heads are not setup for roller cams so you might be doing springs as well.

For lifters you want Morel, they make lifters for many different companies including comp, lunati, crane etc.

Ed Curtis will set you up with the right cam for your combo, whatever it be you choose. He also has good deals on the other parts you're going to need like lifters, pushrods and rockers.

 

So 190 heads on a 347 are too big? What about 185s.

I am running 170s on my 289 so I assumed larger displacement then larger flowing heads.

 

Sorry missed the 347 part....for 302 too big but for 347 I have no idea.

 

Depends on how you're going to treat the motor. If you want a daily driver that's going to spend most of its time under 3k rpm, the 170's are going to be a must. If it's a strip car that spends most of its time at WOT, the 190's may be the better way to go. Keep in mind, Ford intake ports aren't all that restrictive (especially when considering TFS heads), and larger ports make for lower charge velocity, which leads to poor throttle response at lower rpm's.

I have the 170cc heads on my aggressively-cammed 331 and I'm perfectly happy with them. I wind my motor up to 6k regularly.
