91 camaro hardtop
Full street trim with more suspension mods for handling than launching.
330ho crate motor, edelbrock RPM intake, holley adaptor plate, holley 670 with 28psi fuel pressure (custom spring), walbro 255 fuel pump, SLP shift kit in 4L60, 12" 2800 stall lockup TC, 3.73 richmonds, take-off torsen, SLP tri-y headers, Borla cat-back, custom eeprom, open element, removed a/c, harwood 2.5" glass cowl hood, and stock size high performance all seasons. Everything else is stock from the steering wheel to the radiator and driveshaft. Most stock parts have 180k miles. Manages a 13.65 at 103 in typical weather at 800'. That's with picking up knock 5 seconds into a pass resulting in 10 degrees of timing removed for the rest of the run . All in all, great car, love the way it drives but if you want better city gas milage, go with a lower stall converter. 2200rpm should be plenty to run similar times even with the 4-1 headers.

Stock crate motor cam. Specs are 212/222 @.05 .435/.460 lift with 114 ls. It's so mild that she'll idle rock solid at 600 when warm. Any lower and oil pressure gets too low for my comfort and tip in becomes difficult.
Full street trim when I ran those times and I have GOT to fix my slipping transmission. I think it might account for the knock I'm getting in 3rd gears shift, only happens under WOT. Engine revs up scary high if you hold 2nd gear too long.

Another crossfire here, 84 Vette.. 13.73@100.1mph

Untouched stock bottom end
Port matched and de-EGRed manifold
85 Vette fuel pump
15 psi FP
cold air mod
' 89 '113 L98 heads
208/215 @ .050 .459/.480 cam
Comp cams 1.6:1 roller tip rockers
Dual 2.5" exhaust with X-Pipe no cat
Tri-Y headers
Stock ECM
Stock injectors
Stock TB's
Transgo shift kit

This engine wiped a cam lobe a few weeks ago, so I've just pulled it out and stripped it.
The rebuild will be a roller cammed 383 with AFR195's and and X-Ram with 2" TB's and 90Lb injectors, controlled by a '7747. Got the block back from the machine shop today ;-)
Hoping it will run a second quicker than the above setup!
Ben.
