Comments: After driving my 215 powered MGB GT and feeling very comfortable, getting used to the Ford powered roadster for the first time was an interesting experience. This car is scary at first! Incredible acceleration. Awesome sound. Getting used to it was a lot of fun. Thank you to all the BritishV8 members who contribute and share their ideas and solutions on this website.

Ford offered High Output versions of their 5.0L V8 engine from 1982 through 1993.
Ford offered "High Output" versions of their 5.0L V8 engine from 1982 through 1993. Specifications
varied widely over that era. Ford initially used a new thin-wall engine block that weighed only 120#,
cast pistons, two barrel carburetors and a compression ratio of only 8.4:1 to produce a claimed 157hp.
1983 and 1984 engines came with a four barrel intake manifold and carburetor; they were rated 175hp.
For 1985, the High Output engine variant got improved cylinder heads, roller rockers, forged pistons,
and tubular exhaust manifolds; they were rated 210hp. From 1986, the High Output variant included
fuel injection. Various other changes were made and rated horsepower ultimately grew to ~235hp.

Installation of Huffaker Fender Flares

Repairing rust damage by splicing in a patch panel.
Before starting the installation of fender flares, rust damage may need to be repaired.

Fiberglass flares bonded on with Fusor adhesive from LORD Corporation.
The fiberglass flares were bonded on with LORD Corporation's "Fusor" brand adhesive, which is what
Chevrolet recommends for repairing Corvette body damage. After bonding, fiberglass matting was
applied on the inside of the fenders to reinforce the joints. No rivets or screws were used.

A thin layer of Duraglass short strand body filler is built up at the joint, and then carefully sanded back to a smooth radius.

Here's the final result! Incidentally, that's Dan Masters' MGB-GT in the background, and on it you can see
Dodge Omni fender flares. Huffaker flares are a more bold alternative than Omni flares, yet they're more
subtle than the "Sebring flares" the MG factory race team used in 1967 and 1968. Huffaker flares were
created and used by Joe Huffaker's British Leyland sponsored race team, which campaigned MGB cars
to SCCA championship victories in the mid 70's. For a detailed look, see: Huffaker MGB Race Car.
