Maybe you've worded it incorrectly but the LONGER the collector length the better the low end torque. Collector length makes a big difference below torque peak. Primary pipe is about the same, the longer it is the lower the rpm it is tuned for.
Are you going to run the external oil cooler or use the by pass plate ? I know you do not block it off with a flat plate.
If you are referring to the plate just above the oil filter, I'm running the by-pass plate, the one that bubbles out to allow the oil to flow thru. However I drilled and tap'd it for my oil pressure gauge sender. I had seen other guys doing this on another forum, hopefully that's okay and it works okay.
Yeah,I was guessing because the truck headers I have seen before had very short if any to speak of collector. So the truck headers are to kill some low end to trade for more high end then?o No: Derek
I am doing that on my 65 Skylark. Works just fine. Regarding the gas pedal, I used the Corvette style with good success. It is on the small side so I did not have to cut it.
Yes, people have blocked it off lol, didn't last very long... Some company makes a lil piece the looks like a block off though but actually has a passage to let it flow.
Looking good, Im doing a LQ4 swap into my 67 GS. I started it last spring but I had to put it on hold to build a much needed pole barn. Im hoping to have it done by late spring early summer.
Well after a brief wiring issue, I'm on the road... and man I must say i'm very very impressed and extremely happy with it. So glad I chose this route for the powerplant. Going on a road trip to Redding California on the 25th of this month for Kool April nights. Gonna drive the car, stretch her legs on the open road...
Very cool thread- very different project. modern performance in a clean classic. best of both worlds! Awesome!
I love this swap, it runs amazing and has plenty of torque and power.. Runs and drives awesome!.. As far as the gas mileage, haha we are still in the "playing" stage.. However i'm taking it on a good road trip this weekend, Oregon to Redding Ca. and back, So I will track mileage then and post results.
Good to hear you like it so far. The trip will be a good test. This swap is more popular all the time. Keep us informed. Mike D.
Is this the same oil cooler that is between the oil filter and engine on the LT1 engines? Can you just remove it and spin the filter on just like the old 350 Chevy? Sorry to hi jack but since they brought it up.:grin: PS. I know everybody is doing the LS swap and its for all the right reasons.
Well I'm back from my trip. 660 miles of absolute trouble free enjoyable driving experience, and easy on the fuel budget. this upgrade has been hands down the best upgrade I've ever done on any classic car that I've driven allot. I got 21.5 mpg average at speeds ranging from 58-73 mph and going over 2 good mountain passes. Flat ground w/ some rolling hills testing was 23.9 mpg @65mph. I filled up in Redding California and drove straight home 323 miles and used less than 3/4 of a tank :TU:.. Now remember I have very tall gearing. But the whole range of power is still way way better than my stock motor. I can still melt my tire from a start. So if your contemplating doing this swap....DO IT>>
Great swap! The 5.3 in my truck gets 18 MPG with 35 inch mud tires, in a crew cab 4x4 truck, 6.5 inch lift so they are a great engine!
Nice work. LS engines are the greatest thing since sliced bread. The LS2 in my CTS - V just made 570 hp with ported factory heads, intake , throttle body and a set of long tube headers.
Did you have any fitment issues with the accessories our coils hitting the AC Box, brake booster, or steering box?
