Dr.Evil took me for a ride in his car a few years back, and I am tired of talking about doing it, so let's go.

Need some advice and opinions on the best cam and headers for my car.

I don't want an over aggressive street monster. I am looking for a nice idle with a good tune to her. I don't road race, drag race, etc...just want to wake the car up.

I'm going to replace the waterpump and opti as well.

Help?!? I'll have my local tech do the work, so no worries about me screwing something up. I just want to start buying the parts and get on his schedule.

 

Forgot to mention:
Running the stock rear gear. I already have Corsas on the car as well.

 

You could have the stock heads ported and install a Hotcam. That along with LT headers and gears should wake it up..

 

I sent you a reply on the PSP site, check it out.

 

A lot depends on the $ and amount of wake up you want. If you do not plan on pulling the heads off then I would go with the LT4 Hotcam and a set of Long Tubes.

There are several different brands of LT's and each have their own good points, I use Melrose LT's and would use their headers again (skip the exhaust system) and have one built from the existing Corsa system.

If porting the heads discuss your cam selection with them, they know what works with their systems.

Then make sure you get a good tune.

 

LT4 hotcam and a good tune, along with headers, maybe 1.7 RR if you want a little more power than the rest. It would like to have more gear though.

it would have a slight chop and more power, but wouldnt be a monster

 

LT4 Hotcam for sure. Great cam for these engines. Lumpy idle, good low rpm power, and stronger up top. You will need a tune though. Without a tune, it will drive like crap. Add some exotic muscle LT headers and an X-pipe and you'll be good to go.

 

I'd recommend 4.10 gears too. With the headers & HC, the gears will ice the cake and really let you feel that you got your money's worth.

 

Same mods i have on mine and love it! I still plan to run the 4.10 gears which i will be getting very soon! If your going to replace the Opti and distributor, go all MSD. I did and i love it! No issues...

 

BK, who is doing the work? I have started collecting parts myself for this very same venture. You can PM me if you want.

 

SS Works or EM headers. I went with SS Works for the stainless construction. Hot Cam or CC503 for a little more but still very streetable.

 

Sounds like I need to make a trip to Atlanta and do a couple of cam installs for you two.

The hotcam is a good cam for the money and it drops right in with minimal problems. You get to run the stock valvetrain on an LT4 which makes it easier/cheaper. If I had it to do over again I would have went bigger but I wouldnt be satisfied unless the act of flooring the gas pedal resulted in instant death. Anything less only fuels the need for more power. The CC305 is a nice cam and should make similar power to the HC, maybe more but would require different springs.

You'll need (for an LT4)
intake gaskets, get the 777s
timing cover gasket set, this should include crank, opti and water pump drive seals.
New timing chain. Stock on an LT4 is fine
New springs. Stock on an LT4 is fine (about $40 )
Oil filter adapter gasket.
Water pump gaskets.
coolant
Oil/filter.
Ample supply of adult beverage of your choice. I prefer German beer.
Theres a few other things I'm forgetting but that should cover most of it.


Headers are up for debate. I've had my coated hooker supercomps on for a year. I got them slightly used. I picked up 4MPH and at least 4 tenths in the 1/4 with them.


If you really want to wake the car up then consider a Lloyd Elliot H/C package. at least give him a call and discuss it with him.

 

Where are you located? Just curious...

 

As headers go, I would go to Em for them. They have extensions for Corsas to hook up to their LT's. Can't go wrong with a Hot Cam either. I agree with Vader, need to go to a lower gear.

 

Will the 1.7 rockers be ok with piston/valve clearance?

I may swap my 1.6's out for that extra lift...

 

I've told you many times, I'd fly you here and put you up for the weekend. Fly you home and back if needed for a 2nd weekend.

I just want to get all the parts together including a water pump, opti, new springs, etc.


Josh, I have a call into David Fulcher to see if he'd be willing to do the work.

 

Anyone know if the 1.7 rockers can be used with the hotcam with any clearance issues??

Sorry to thread jack but i figured it would be a good question for everyone to know the answer to.

 

I'm in East Tennessee, just North of Knoxville.

I know there have been a couple people try the 1.7s like Nathan Plenum on his LT1 but I dont think you'll have any issues with the 1.7s on an LT4. It takes your lift to .558 and our heads can use the extra lift. I've thought about trying it but I still need to do a couple other mods first. Alos, AFAIK no one makes a self aligning 1.7 RR so you'll have to have guideplates and hardend pushrods in addition to the new springs.

 

Brandt, I'm coming down to Braselton the 16th-17th of May for the year one event. I actually got picked to race for Vette magazine in their magazine shootout during the year one event.

 

Not to mention studs, as the LT4's came with 10mm ones.
