Ramon Lowe 58 Pontiac

[FED 387]

McKellar was the engineer from Pontiac that created/designed the OHV engine for Pontiac---- he was an authority on the subject of valve train/camshafts etc... Melling provided mamy the hi-po camshafts to GM and they had the "masters"--- Might check with Melling about McKellar cams & specs--FED387

The 'Entry Level' Pontiac for 1958

Mine was white with a blue cove and roof....Very nice paint done by a well known local body shop in lacquer.......I waxed it every Saturday in 1965.....I loved that car! I installed an interior from a '62 Olds Starfire and it looked much better than the factory cheap seats......

Did Pontiac use the same FI on the Chevy?

A friend of mine had the 327/375 back in the days.
Said the injectors got fouled up on the leaded gas.
One of the reasons the gas became unleaded.

The Pontiac F.I. unit was made by Rochester just like the Chevy so yes they were similar but did not interchange in anyway,,,,

The Pontiac unit fit Pontiac heads...had a separate water crossover manifold and a mechanical drive type distributer.

I never worked on any F.I unit Chevy or Pontiac so my knowledge about them is very limited.

The Pontiac F.I. unit I had sat in my basement for a few years until I sold it.......I recall paying less than $100 for it and selling it for about $300. I can only guess what one would sell for today....but know it must be thousands of dollars....
They used very small copper fuel lines to nozzles in the intake as I recall.....and the distributer drove a pump....but I have zero hands on knowledge here and it has been about 40 years since I even saw one !

I had friends who raced them on Chevy's and had no problem with them but you had to know what you were doing with them for sure....and they did have a bad reputation on street cars like Corvettes......The rap was that they leaked and were hard to keep in tune and caused fires......

I worked on a lot of HP cars in the old days.....Never once worked on a Fuelie Corvette and never, ever saw a F.I. Pontiac on the street...very rare units for sure....

Rich B,

Thanks for the follow up.

From what I found in an old Magazine Article.

Part I

The 1958 Bonneville was to be made available with the
* 370/300 HP ~ '3 x 2' Barrel'
* 370/310 HP ~ 'Fuel Injection'

This combination was only to be available with the Bonneville Model.

Featuring;
* 10.5-1 Compression-Ratio Cylinder Heads {65 CC}
* High-Lift Camshaft


Part II

In March 1958, an 'Extra Horsepower' Nascar Certification version of the 370 was available.

Featuring the "Tempest 395-A' code.

PK Option = $233 {Available in all Models}
* 370/315 HP ~ '4-Barrel'
* High-Lift Camshaft ~ {Dealer Installed}

PM Option = $331 {Available in all Models}
* 370/330 HP ~ '3 x 2' Barrel
* Special High-Lift Camshaft ~ {Dealer Installed}
* Special Exhaust Manifolds

The 370/338 HP 'Fuel Injection' must have been an 'over-the-counter' performance add-on.

The car I got the F.I. off of was a SuperChief and it was a very rare model.

It looked totally stock.....and had the F.I. emblems on the front fenders and they looked like they were factory installed...

Pontiac made 2 different wheelbase cars in '58 I believe

The Bonnevilles and Super Chiefs were the longer wheelbase models

The base model Chieftans and Star Chiefs were the shorter wheelbase.

My memory is only so good after 40 plus years...and I do think the T part number for the HP parts was for Tempest and not Trophy as I posted earlier....

My local Pontiac dealer had a real great guy behind the parts counter and he put up with me inquiring about those T-395A manifolds and tried to get them for me....

A few years later I bought a very nice '60 Catalina Convertible from him...and also went to work at that dealership as a line mechanic and was there in the mid to late '70's......Not much of a performance era,,,,I did work on a lot of TA Firebirds but never saw the Bandit....LOL The only Bandit was GM......cause they sold some real junk in that era,,,,,
