Although Slaney really makes the most of the time he has to cruise and race the '85, he's also been making further improvements. The biggest of which concerns the engine. "My GT went a quickest of 12.49 at 110 miles per hour with the 306 under the hood, but last year I got the speed itch again, so over the summer I pulled the 306 and dropped in a 337 stroker." This engine uses a 1970 Windsor 302 block, which Paul bored .060 inches over and set up with DSS internal goodies, a Comp Cams 294 solid roller bumpstick and a set of AFR 185 cc aluminum heads, Edlebrock RPM Air gap intake and Holley 650 cfm double pumper four-barrel carburetor. When the T-5 gearbox let go, Slaney swapped it for a Tremec 3550 five-speed manual and since that time he's been more than happy. "When I got it all back together I strapped the car to the dyno. It made a big difference. I gained an extra 80 horsepower and when I took it to New England Dragway, the car went from being a solid mid 12-second runner to deep into the 11s."

But, before you start thinking that he's planning to go the all-out drag car route, Paul had this to say. "As much as I love taking it to the track I think I've just about reached the limit with this car. I like driving it on the street and I don't want to cut it up to put a cage in - so it won't go beyond an 11.60 car. I've had this GT so long that it's special - it's a great, clean car and I just like driving it and taking it to the track. Besides, I've got my hands full with other projects anyway." Said projects include the '88 GT convertible and also building a 347 cube stroker that's going in his brother's car. "I really enjoy doing this stuff, it keeps me busy and myself, along with my brother and cousin just love these cars. When the weather breaks for the spring and summer we enjoy getting together and going to car shows, cruises and the track. We'll be out and about this year, doing the Mustangs Unlimited shows down in Connecticut as well as going to New England Dragway and probably the Fun {{{Ford}}} Weekend event up there in August. There's nothing quite like it." Indeed, and, as well, there's probably nothing like prowling New England streets in a car like this and dispatching a few jokers who think they can take you on.
