Anyone try this swap yet? I was thinking about it since the 455 E-Head EFI engine I want to do might be too expensive.
I was thinking about it. IT would knock about 100-150lbs off the front end compared to a 455. Plus I could easily bolt up a T56 or 4L60E tranny. Any thoughts about this swap. And I guess I would rather keep the 455 for Drag duty. ------------------ 1966 GTO awaiting restoration, 1999 Ram Air Trans Am |

Oh. I see.
Do these engines, along with their respective transmissions, yokes, computer control systems, engine swap brackets, headers, etc., come cheaper than do real Pontiac engines? |

Well, the LS1 is not painted at all. All natural aluminum.
2nd, don't tell the guys at MTI in Houston, www.morganmotorsports.com or ARE Racing in Canada that these engines can't be built to go. Some guys who just installed a cam into a stock engine, are turning in the neighborhood of 360rwhp. That would be over 400 at the crank. Dave, the heads won't warp. As any of the people above about these engines. |

Hey Mike I know a little bit about IH power I used to drive a scout 4/WD back in 76-77(it would go anywhere but had horrible electrical system).
With the 6.2 throw a turbo & an intercooler on that old oilburner and you are good to go.Go burn down some grand nationals with your tubo Delta 88 land barge!! Later Mark B. ------------------ |

before it blew up, my LT1 had ported stock heads, hyd. roller cam (230/236 duration), long tube headers, 36# injectors, electric water pump, SPEC clutch and some other bolt-ons...probably about ~$4000~ worth of mods in total, not counting traction stuff, gears and rear end cover. from what i've been able to gather it was probably one of the 10 quickest/fastest NA, stock bottom end 6-speed cars in the country.
i'm not claiming that LT1's are faster than LS1's, i just love to needle the LS1 crowd.  it's well known that an otherwise stock LS1 will run well over 110 with a relatively small dosage of laughing gas.97 Trans Am WS6 Best ET: 12.13 Best MPH 114.6 74 Formula 455 Best ET: 11.97 Best MPH: 112.58 |

Who needs fuel injection for a more reliable motor? I had injectors go bad. It is a machine and will brake with time. I drove my GP alot in high school and never had a problem with the carb. Now the trany,
 well that is another story along with the tires  Do what you want it is your car but I would rather see a ratty old Pontiac motor in a Pontiac than some redone Chevy,  I meen corporate motor. It was after all designed for the Corvette making it a Chevy?

Well, the price is nominal. A LS1 out of a wrecked F-body will run around $3000. A aftermarket harness and computer is another $500. Then I would have to buy headers $700.
The 455 I wanted to build would cost a fortune. THe EFI unit is around $2700 all by itself. Then I need the E-heads$2000, headers, etc. I could pull the tranny along with the engine. The only problem I am looking at is the motor mounts. |

YO Mrgto,Why would anyone on a low budget spend all the time and money to reto-fit a modern puter controlled USED motor into an old car when the can get more HP per $$$$ staying with the older carb setups???
I have made a living for 20yrs. wrenching for as an ase master tech,state DOE certified tech,w/many other tech puter certs.  My main point to the mans ?? is, if he doesnt have the proper diagnostic tools and knowledge,he will be over his head at the most minor drive-ability problem.. Most ECM controlled cars are reliable,I agree,but to the average back yard mech. I cannot truthfully recommend he do it,especially if hes on a limited budget !! [img]/infopop/emoticons/icon_biggrin.gif[/img] ANYMOTOR can be made to run, example--> Brigs@straton lawn mower engine in a JR dragster class,if ya got the $$$$$$... And it dont have a puter..

I never said they can't be built up! Just go ahead and try to Bore one... They have to use stroker kits to get bigger... I have a lot of friends with ls1 f-bodys and they do run great. If you really want a new motor in an old car, buy a Chevelle...

I agree with the guys above I have done numerous engine swaps and they are never easy.You better be a good fabricator or have very deep pockets.If you expect to finish the job.
You can build a traditional Pontiac without E-heads that will rip a LS1 apart. My Iron headed 455 makes 580-600H.P and 600 ft.lbs of torque all day long. Another point to consider is resale value who wants a Bas#%*d engine in their classic pontiac GTO I bet not very many people. The LS1 will NEVER make the torque that a Pontiac will. I could understand a 400-455 swap in a late model T/A thats cool. But not the other way around. However it is your car so do what you want dude. Good Luck ------------------ |

A 6.2 GM diesel? C'mon, guys. That thing's a bigger piece of crap than the Olds 350 diesel. At least, with bigger head bolts and improved head gaskets, the Olds 350 can be rebuilt to be reliable.
If the 6.2 isn't breaking cranks every 6 months, then it's cracking cylinder heads between the valves. No thanks! |

For those of you wanting to follow the LS1 project I started a new topic
For Rumair, sure stock LS1's may be slow compared to certain motors, but it will eat a stock LT1 for sure. I'm sure your 12 sec LT1 is "stock"-- right, or it only cost you a couple hundred to go low 12s. Do your car buddies believe these stories, cause if they do, I have some stuff to sell them. |

Why spend all that $$$ on a small block when you can buy a 502c.i. HO 440 hp from GM along with a warranty,new?? No computer bs involved,and its got torque like a built Poncho motor...
You can also get a complete zz4 350 ho new from chevy with aluminum heads,intake,ditrib.waterpump,balancer,oil pan,etc.and a new motor warranty..For $2,999.95??? That ones rated at 355 hp/405 ft-lbs. torque....I prefer Pontiac motors in a pontiac,and vis-versa,but what ever floats yer boat.... [img]/infopop/emoticons/icon_biggrin.gif[/img] steve.

I've also been thinking about a late model engine in a classic vehicle. My idea was a Z06 Corvette engine in a 36' Pontiac Coupe. The car isn't super rare or anything so totally customizing it wouldn't be unforgiveable. I wanted to use an interior scheme from a late model luxury car, custom paint job etc. Basically the power of a late model 'Vette, comfort of a Mercedes, and the looks of a 36' Pontiac.
I guess it all depends on what you want to do with the car. If you want to race, stick with the 455, if you want to cruise, and do something different then go with the LS1 if it interests you, but know the extra effort you'll need to put into it. All the guys have made good points, but in the end it's your car and your choice. Since the 66' Goat is one of my fav's, I would stick with the true pontiac iron if I was restoring one. But I say do what you want. [This message has been edited by Maniac (edited 11-18-2000).]

scott, the later 6.2's were a decent engine. all the 5.7 olds engines were junk. you might find 1 out of a 1000 that ran 100,000 with no problems. the 85 and up 6.2's that we sold had no major mechanical problems, the early ones did have bottom end problems.mike

A GTO on the road with an LS1 is better than a GTO sitting behind somebodys house on blocks - no matter what the diehards say

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
