Whats up my fellow regal owners! I'm new to the page and I'm looking for some insight. I have an 87' regal limited with a 307 olds V-8 but I have a 74' 455 being built as I'm typing this. I want to have a respectable street set-up. Heres whats being done to the engine right now- Heads being ported and polished Stage I (2.125"/1.75") valves being installed into head HPT piston upgrade(9.5 to 1 CR) Aluminum rockers Camshaft upgrade w/springs (for power up to 5200rpm) I provided the machine shop with gaskets for the TA long headers as I plan to run dual exhaust. I've yet to see this completed transplant in action. If you guys have please provide feedback. Thanks
I have a similar set up going ... What motor mounts are you running? I was looking for some solids -- what cross member and tranny will you be using? :blast:
I'll be working with a th400 tranny. I'm thinking about getting the motor mounts that TA performance is offering. As for the crossmember, my old man has a bunch of GM crossmembers and he modified one when my brother was working on a similar project.
That should be a respectable car what size cam are you going to use? Are the pistons you using flat top or dished. The one good thing about buicks is it doesnt take alot to go fast
The cam and springs are from Comp-cams (.050 duration, 112 lobe sep). The hypereutectic pistons are dished. Also does anyone have a recomended tire/rim size combination thats good for street use? Coker tires offers a nice BFG set of letter tires but they are 14" Thanks
15x7 up front and 15x8 or 15x8.5 on the rear. This will generally give you the best overall combination of tires, handling, traction, wheels. Most people generally prefer 215/65/15s or 235/60/15s up front and 275 or 295/50/15s or 275/60/15s or even 255/70/15s in the rear depending on what gearing & looks etc that you want. Naturally proper backspacing and or a spacer may be required for some of these tires. I have used 275/60/15 M&H, MT, and Nitto drag radials on the back. For something that is mostly a driver I like the Nittos the best. They do provide way more traction over regular radials and have respectable wear and wet weather traction for a drag radial. Generally the taller the tire the better the traction. Food for thought. If you plan to drive this car a lot in the summers and actually put some miles on it such as with an out of state trip car show/drags Buicks at Bowling green etc. You might consider building that 2004R. If useing the same gears say 3.73s with an OD + lock up converter + manual lock up + maybe a Q-jet as oppossed to a Holly, and you went from say 11 to 16.5 mpg you would use 50% less fuel. Naturally it would takes some miles & saved engine etc wear to recoup the extra $1,000 dollars that this might cost but at 2.50 or $3.00 a gallon it might have you actually putting some miles on it instead of looking at it in the garage.
Vern, thanx for the feedback about the tires. I have an 01' monte carlo that handles the bulk of my daily driving duties and out of town trips. The regal is mostly for the weekends the 15x7 frt/15x8 rear looks good on the g-bodies.
