The Stock Car Classification Guide puts the 90 convertible LX at 3168 and the GT at 3197 shipping weight. 302/225, right?

Re: Ford vs Chevy Build-up
 

I've been using the stats here on the forum... http://www.classracerinfo.com/Default.aspx

Let me go check the NHRA site for changes...

Edit - It appears there was a hp hit across the board for the 302 (225hp). Whats confusing now is the weight is greater for the '89 than for the '90...was reversed. :confused:
'89 - 3394 pounds
'90 - 3312 pounds

I guess it was because the '89 gained 10hp from 215 whereas the '90 only gained 5hp from 220.

Lol...this is all wrong dammit...there were no changes for Stock.

Re: Ford vs Chevy Build-up
 

Looks like a fun project, good luck. You might want to contact a friend of mine who is on this forum. He has a 89 mustang convertible that he runs in P/SA. He also has a 92 lx coupe that he runs in SS/MA. The stocker is usually around the .500 under mark and he does it on a budget. His user name is fordteacherguy and his real name is Brian Thompson. PM him and he will help anyway he can. Brian is very knowledgeable and a very nice guy to talk with. Can probably give you some advise to help save money. Good luck.

Thank you sir...I already have a pm waiting in his inbox as we speak. :)

If you are going to put subframe connectors in that are worth putting in, they need to be through the floor. Not under the car, especially a convertible. These cars flex a lot with a full roof. You may want to search the forum, as there has been a lot of advice on rear suspension and how to fix and support it too.

Re: Ford vs Chevy Build-up
 

I figure a roll bar will help with chassis twist/flex as well, but I'm open to all suggestions. Keep in mind the intended class and likely power level. I have searched the forum but came up with little detailed info on these cars. I have found some useful info on Corral.net tho. Does anyone know what the exterior differences are between a '89 and a '90 GT convertible?

Re: Ford vs Chevy Build-up
 

When I started working on my 68 coupe, I could jack the right front torque box and just lift the right front wheel. Now with a full cage, weld in sub frame connectors and a bolt in x brace, the same jack point lifts the whole right side of the car. Stiff as a board. The connectors aren't through the floor, either.

Do a google search on "Mustang roll cage" and click the Images tab. you will find a lot of builds that include connectors both under and through the floor.

99.9% sure that they were the same. Except for the switch to the bigger brakes/ 16" Pony wheels in 1991 I believe the styling remained the same.
