Hank the 15.15 was with the stock 3.08 gears and 3rd gear Never hitting 4th gear. And this spent most of its days a s a daily driver,When I finely got aroud to gettint the gears in that IT SHOULD of had when i frist built the motor it should have been running in the 13s. But as time went on and this started to show signs of some blow-by ( nearing the end of 17s running track & daily driving)the car ran a Best of 14.3 in 3rd gear with a set of 5.13s
And if you readit right I said It was a GUESS of between 13.9-1 to 15.1 We did NOT have FULL CCs we only guested We knew what the CCs at that time whatthe head had. But no clue as to what the Bore & piston had. It was a 194 head that had been Milled a few times Before I ever had Blew a head gasket which Burned a Notch in the head .010 deep.
Anyway It don't matter at this point. That 17yr old plus motor Has now been Rebuilt which Once i get the Valve cover done & side cover The New motor should be in sometime after the first of the year I Hope. With the same pistons now floated
and a little more milled off the top to now clear the New cam specks are .69111/.68057 dur.is a 269.2/272.7 lobe separation about 105.5 the valve over lap 58.9 crank deg. Now as for the compression I was after no less then 12.5-1
13.-1.I was going to gas port the pistons but didn't But a fire slot was done this time.
I have to open the block up to change out the head gasket Because they didn't not Install the right one. I will get pictures Of what the piston
Now looks like compaired to before. I also need to double check the Push rod to head clearance Because of the lenght being 10.400.
Now as to what the car weights With me and a full 18gal it tips in at 3000lbs This is a ALL STEEL
and all stock glass bodyed car with Tubs 8 point roll bar and all Inter.(including a back seat for two).SO a 14.3 in 3rd gear on a 17yr old plus Motor I do not feel was so bad.
This new combo should put me some where in the low-mid 12s we figure.without making the car lighter.
But we'll see and go from there.
God doesn't like ugly.
