Thanks to you guys and reccomending a skip white hei...I ordered one up and got it Friday..
Install went smooth as I ready every post here pertaining to the swap...Piece of cake.... Got some new 8mm hei wires and gapped my new plugs to ..45.. FIRED UP FIRST TRY AND IT SOUNDED LIKE A NEW ENGINE.. I cannot believe how smooth she runs now and the throttle response is unbelievable....My new flowmasters have a completely diff (much better) sound. This is by far the best upgrade I've made and the best part..only about 100 total! ![]() If anyone is thinking of the swap..just do it..you'll be glad you did. ![]() Next project...get the a/c working..(everythings there but have no clue where to start) |

Mine didn't change much, but I need to replace the spark plugs and wires, and my carb is shot.

Re: HEI Install "WOW"...wy'd I wait so long....
That's the first thing I did to mine when I got it. I had one that I re-curved for my 383 that I built.... it's close but it still gotta run my timing lower than i'd like.

Re: HEI Install "WOW"...wy'd I wait so long....
First thing i did was adjust the distributor til it was just right, then adjusted the carb (was too lean) and that thing (71 longhorn) ran like brand new!
defintely the BEST upgrade i ever did. the worst upgrade? headers ! So many headaches since i added the headers. Never again.

Unfortunately I will have to live with mine for now, until I get the ambition to unbolt the engine and lift it way up while having the truck way off the ground to remove them. It seems a good deal on headers sometimes is more trouble than they are worth. My son swears by headers, but since I went with a stock 454 I am not sure they were an advantage. Danny

Re: HEI Install "WOW"...wy'd I wait so long....
You don't need to lift the motor up and get the truck way up in the air if you're gonna toss those headers in the trash. Cut them out with an angle grinder or a hacksaw. I've done it.
