You've come to the right place. There's lots of great people here, and lots of knowledge here that I've been fortunate to tap to my benefit. Post pictures of your car - we all want to see it!

My car has the motor out right now.
The old combo was a top end job.
I took the heads off and put big valve's in.
New hydraulic cam from Ultradyne 270/274 219/226 .491/.499 108/104
Short block had a 170,000 miles on it very tired.
Measured 9.14cr,about 175-180psi cyl pressure Cometic head gasket RPM intake and 1 3/4 headers,750dp.
2800 11'inch PTC converter flash was about 2400rpm.
3.90 gears th350 27" 10.5 tire ET street.
The motor put 266hp to the wheel @5200rpm.
I figured about 330 crank hp.
Track times were with full exhaust race pro mufflers x pipe.
60..... 2.007
330.... 5.668
1/8.... 8.746
miles per hour... 79.24
1000.. 11.447
1/4.... 13.747
miles per hour... 97.84
In crap 4500ft air.
Now block 30 over Probe pistons,ported heads that flow 255 at .500,10" 3800 JW converter,crank turned 10,10 reworked stock rods,cam NF 72 Bullet solid FT 275/275 247/247 .566/.566 106/106.
Compression comes in at 9.89.
No times yet because can't get clearance on mains will need to go back to machine shop.
This should be in the 410hp plus range at the crank will see.

73d88...there is a really nice 73 D88 in Florida on eBay right now. $13,888 buy it now. Mate of mine here is trying to rustle up the cash (it'll owe him $25,000 by the time he pays shipping, taxes, engineering etc). Never really taken much notice of the "big" Oldsmobiles before but this one has got me taking notice from here on.
