The 327 9.5:1 compression. Flattops with valve cuts. The guy I bought the heads from said they came with .600" lift springs, but he had them changed to .550" springs. He didn't want more spring than he needed for the cam he planned.

 

I hate you.

 

Sorry Damon, but not real sorry!

 

Can you tell me if the heads are older 195s or the newer Eliminator AFRs? If you picked up the latter you are in for a real treat. Either way they are tough to beat. The newer ones are a big improvement over the older ones. Not like they needed it, AFR just did it to raise the bar a little.

If you got a PN I have an AFR catalog I could look them up in.

 

Not sure which they are Damon. They're all wrapped up and stored away until winter, as I didn't want to tear the car down until the good weather is over. Still gathering parts for the winter projects.
Have to order some rockers, and the cam/lifters yet. Not sure on what else I'll do.

 

My buddy and I went to the Hotrod Nationals at Woodburn Dragstrip today. Drove our Austin gassers so we could have some fun cruise time. I've never cared what I got for mileage, as I didn't build it to be an economy car, but he wanted to check his.
We filled our tanks prior to the trip and did a 100 mile roundtrip to the drags and back. Filled again when I got home and used just over 6 gal. of fuel! I averaged about 15 mpg with the 327 and 3.73 gears, going around 55-60 mph both ways, with very little stop and go traffic.
Was a pleasant surprise, and much better than I ever dreamed it would get. Were taking another trip up to the Cascade Mountains tomorrow, so more up and down driving. About the same distance, so see if it uses about the same amount of fuel.

 

Sounds pretty nice on the mpg.

I've always been a big believer in customizing the springs to the cam profile. The springs will have a longer life and increase valve train stability. Add some spring locators to the base and be done.

 

Yeah, when he explained to me why he changed the vale springs it made sense for a couple reasons. Why have the extra spring pressure if you never go that high?

 

Right, too much spring pressure can kill a cam.

 

Ya gonna go roller Val?

The guy set my springs up too soft on purpose because he thought I was running a flat tappet. I was so pissed when he told me and then defended it with saying. You can just put a +.050 lock in it to get the pressure close. The cam card I gave him said roller on it. The card also called for 110# seat pressure and he set them up at 90#.
