Re: Aluminum vs iron heads on a 9:1 daily driver
If you have to buy heads, then have them gone through. the weight savings and the fact that you can buy a decent aluminum head set for 1100 or so (afr enforcer, or comparable) make it a no brainer to go aluminum? Unless you have a machinist working for free and can buy springs cheap the current crop of as cast aluminum heads shouldn't be ignored. Plus they give you room to grow. Just my $.02 your mileage may varytravis wrote: ↑Sat May 14, 2022 4:30 pm Is there any advantage one way or the other on a mild 302 sbf? 3300 pounds, somewhere in the 3.55-4.10 gear range with an AOD or 4R70W. Around 9.0 compression, small hft cam (either 208/208 on a 111 LSA, or 214/214 on a 108...I have both). Shorty headers, low rise dual plane and a small 4bbl. Just a driver/cruiser.
I was looking for a set of GT40P heads, but wondering if aluminum heads at this level is worth the expense.
