Hi everyone,
I have multiple questions regarding LS engine in a 33 hot rod. I have been working on putting this build together for a while now. I am a research and then implement type of person. I have a few questions left then I am ready to throw down on a kit. I already did the build school.
1) Hood /Engine Clearance:
I had the opportunity to build an engine before ordering a kit. I was told from the factory, that a Vortec engine would pop right in and fit under the standard hood. So I made sure that no matter what I did, the new intake was equal or lower than the Vortec intake. I ended up getting a Holly Midrise intake which matches the Vortec height. But then I was in Scottsdale for B&J auction, and saw an LS car. I am not so sure it will fit anymore. I was hoping someone else has an LS under a standard hood and can measure from the engine block "Plane" to the bottom of the hood around the area of the Throttle body since that will be the highest point of the engine. I am assuming a L Square off the block (not valley cover) with tape measure will work for this. Any help would be much appreciated. I am sure the extra clearance hood will work, but I like the look of the standard version. I am on the fence of changing the intake or getting the extra clearance hood.
2) Affordable Silicone Air Intake Tube 92mm
I have been told multiple times to make sure I do not put the filter right off the TB and make sure I have at least 10 inches of tubing. However I see others that have done this and are racing that way. Is there anything with simple Black Silicone under $100 that will work? Everything I see is gaudy and $400. What degree of bend do I need to clear the radiator and engine? 75 degrees? 80? This will just be a street car and black fits the color scheme. Honestly I do not like the look of the big tube and rather put the filter off the TB. Yes, I know it hurts horse power and such, but does it matter for a street car running 400-500 HP in a 2000lbs car? Or is there all sorts of idle issues etc?
3)Coil relocation
Due to my valve cover setup (vintage hot rod look), I would like to relocate the coils. Has anybody done this? Off the firewall seems to be the only place. Out of everything I have researched this is what I came up with. Proform 69520 Coil re-locators/ TSP 81020BK (60) 81015-8 (192) 81024 (60) 81021 (24)/ MSD Wire Comments or suggestions?
4)Tuning
I have a 370CI LS 2004 Blue/green computer, 6.0 30 over (370cc), Holly Midrise, 36lb injectors & hot cam. Locally they want $600+ to get a tune. I am not racing and just using for street use and on a budget. This engine is so overkill for this car it seems I could possibly get an unlock and generic tune that will be good enough for $100-150 by sending it somewhere. It is not about maximizing every drop of HP out of this thing. Of course I want it to idle correct etc.. I was going to use PSI wiring and the stock computer. Any comments? Suggestion on where to get a decent setup and unlocked over the internet? I know PSI will unlock, but they said do not bother if you are going to get it tuned. (It seems like it is more of an unlock then any suggested parameters being entered.)
5) 4l65e - Stall and Lokar shifter
Suggested Stall = 3200-3500. Any comments from anyone that has done this? Is 3200 barely enough or 3500 too much? I see a Lokar shifter available, but I do not know if it needs to be Trans mount, Floor mount or floor mount with cable. Also I would like my arm to be relaxed like most cars at a 90-110 degree angle at the elbow. I am assuming the shortest one they make which I believe is 8 inches for automatic? Any guidance or part numbers?
6) Transmission Installation Kit: 19259117
On the Connect and Cruise GM page I see there is this installation kit. Is this something I need to mount this trans? So far I am thinking no.
Thanks for all your help!
