Default 66 elcomino+cammed ls1=?

Hi, i just joined the website. i have been watching it for about a year and noticed all the conversions do.Anyways i just bought a 66 elcomin out of texas.Floors had rust but nothing else. Replaced them and now thinking motor. I know i want to do a cammed ls1 and t56. How hard do you thing this will be? What cam for a daily driver. I think it's got to be fairly mild for 11-1200 rpm's ant 55mph.The car is going on bags and is going to be my daily drive. NOt worried about time, cause i have 8 months to get permit.

Thank's

What rear end ratio would it take to achieve 55mph at 1100rpm? Anybody?

Depends on the tire diameter.

Yes, the stock one

These motors make good power all the way to 7k and they have smooth idle.

Do you want a car with a nice idle and good low end ?

I would maybe do the ls6 (good for 15ish hp over stock)

JMHO, I think 1100 is too low, unless you have a way light car. Are you talking 6 spd or automatic? For reference I have I have 4L60E, 29" tires and 3.80 gears and I am at 1700 at 55.

If you go with a T-56 6 speed you should be able to keep the rpms relatively low even with 3.73 rear end gears. Alot of people say that something like a 224/224 cam with some like .56x/.56x lift would be a good mild daily driver cam. You can make any cam daily driveable with a good tune and driveability is in the eyes of the beholder. Many people with 4th gen F-body's love their Trex cams for their daily drivers. Personally I am going with a 228/228 .588/.588 on a 112lsa for my daily driver. Its up to you really.

I want low end power but also want a good sounding idle.I'm thinking 6sp. I dont think 1100 is to low cause my friends 01 ls1 camaro has 3.50's and runs 1100 at 55mph.

My rear end came with POSI 4:11's so I'm not messing with it. Plus, most Chevelles/elkies run bigger wheels nowadays and that must be taken into account in the gearing.

i own a 66 elky as well....i ended up stuffing a 455 stage 2 motor and a auto w/ overdrive in it since i am using my lsx motor and t56 for my 52 styleline... mine had 3.73's in it stock, so i would venture to say yours prolly does too.
