Ok so I just ordered a new set of gt40 heads for my 87 mustang. Now im looking at Pistons. Are the stock ones good or nah? Im looking get a supercharger as well probaly between 5-8psi. want to make sure i have pistons that will hold up. Also what about the rods attaching to the pistons, someone told me that the stock piston rods are fine but what to get a second opinion. thanks..

If things are in order. The rotating assembely will outlast the block.

So your saying i should just leave the stock pistons in there? Will the piston to valve clearance be good?

remember GT40 are a stock Ford head, so you will be fine.

I'm in love with those keith black pistons but still stock are still good pistons

 

[ryans88gt]

the stock pistons were made by TRW and are some seriously heavy forgings... the stock pistons in a 87-92 block will take more than double the hp the block can handle

Well go the the net and find it out there are many sites that will help you better

Sorry Forgot to say it in the first thread and it was the reason for this entire thread. I also ordered a new cam. Ford racing F303 Supposed to be great for superchargers but it says you may have to check piston-to-valve clearance. Thats why im trying to figure out if the new gt 40 heads will make a differance where they will clear or if i have to replace the piston all together. Thanks..

People are gonna gripe that you actually spent money on that cam

 

[93hatch]

goddam its expensive, prob coudla found a used one on corral for 80 bucks

 

[Iwannagofast]

i seen people give away alphabet cams

From what i've read/seen, people CAN make good power with F cams, but if your going to buy new, hit up Ed Curtis or Jay Allen -- especially if your going blower/turbo - they can cut you a nice grind to help with drive ability and milk more hp out of it.

 

[ddarkslayer]

yea I found cams for 60 to 80 on craigslist in my area

 

[ddarkslayer]

the blocks are strong but there not the strongest I believe the HO blocks are good to 450 hp

Well i was told it was a good cam anyways i didnt pay for it friend or mine has some connections with summit and when i ordered the gt40 head he threw in the cam at no charge. But i want to make sure it will fit with the stock pistons.
