anyway to tell what hp my 58 was originally?

[Brandon T.]

As of now it has a 1960 dated 283 in it with camel hump heads and edlebrock high rise intake with a holley carb, and the trans is a 64 or 65 muncie.

haven't checked rear end I assume it's original though.

car is stock body wise etc just hop up's like this were done question is can I tell if it was a two 4 car or not? I know it wasn't a fuelie due to the tach.

the car is an original 4sp car the shift plate says 4sp and I bought this car from the 2nd owner who bought it from the original owner in 75 with these mods done already and he said he never touched it just drove it.

thanks

In a word, no, the car is 49 years old, even though you bought it from the second owner, lots of things could have been done by the first. Without some kind of original paperwork there is no way to tell, it could have come with a three speed and open rear end. If the motor was replaced by the first owner, chances are it was run pretty hard. Unless you are looking for that ribbon just drive the car and enjoy it for what it is. Just my old 2 cents!

Brandon, low redline tach is hydraulic lifter engine, high redline is solid/mechanical lifter.if the tach is original to the car. What rpm is the redline on your tach?

Re: anyway to tell what hp my 58 was originally?

tech reads to 6,000 rpm

redline i guess is 5,000 or a little over the 0 in the 5,000 mark is red and has a line there...

i already knew by that it wasn't a fuelie just trying to narrow it down a bit more, so what does that info narrow it down to? a 230hp or 245hp car or what?

Brandon,

What is the approximate build date of your car? I'm just curious if it's close to my '58 build date.

That would be a 230 or 245 horse car. Which is hard to tell with the original parts all missing. I was thinking maybe the throttle lever would give a clue but all 58-60 non FI, non powerglide used the same one.

Does it have an original dual point distributor and what is the date on it if so?

Correct me if I'm wrong but couldn't you get a fuelie with the low rpm tach?

I thought there were high and low rpm dual quad, and high and low rpm fuelie engines? The low rpm ones getting hydraulic lifters and the high rpm ones getting mechanical lifter?

Sure doesn't and it has a holley on it now so not sure about the throttle lever.

but atleast I know it was a 230 or 245hp car. I'm wanting to go 2x4's with it and make it out a 245hp car which it coulda been in the first place I doubt it due to the original owner buying it new at age 18 he probably bought pretty much a base car it did some factory with the 4sp tho.

Brandon;

Hydraulic (Low RPM):
Single 4 BBL
RPO 469A/B (PG or Manual) 245 HP dual WCFB's
RPO 579A/B (PG or Manual) 250 HP FI

Mechanical (High RPM):
RPO 469C 270 HP dual WCFB's
RPO 579D 290 HP FI

If you have the original rearend check the ratio for a possible clue.

thanks Steve I'll look tomorrow.

Re: anyway to tell what hp my 58 was originally?

if I go with a 230hp setup is this the correct intake manifold? http://cgi.ebay.com/ebaymotors/1958-...Q5fAccessories

says it's off an impala but is it the same thing as the 58 230hp vettes had? if so that is cheap for it IMO.

Re: anyway to tell what hp my 58 was originally?

The intake used for the single four barrel setup (230 HP) is part number 3746829 and was used on 58 Corvettes. This is a one year only intake.

Thats the part number of the intake on that ebay ad so IMO 50 bucks is cheap for it I'll have to run my vin number to kinda see if it fits the car date wise incase I ever decide to put a matching date engine in the car I'll already have a matching date intake manifold.
