I know it is not a Chevelle, but being that it is an A-body, I thought many of you might be interested. As many of you know and many don't, my 1970 GTO was done in October of 2002.

Since then it has lived a rather quiet life. Mostly in storage. Due to some issues in my personal life and a lack of interest, the GTO was a bit neglected over the last 4-5 years. Well that changed this past weekend. I finally sold my fuel injected 502 big block. The engine will have a happy home in a Chevelle.

Stay tuned for more details and future upgrades and pictures.

Glad to see you back Andrew. Chevelle or not I'm sure your welcome here. I for one will be looking forword to seeing what you have in store for the next generation of your 70 GTO. Lots of new stuff since 2002 .

Some sort of LSx engine. I haven't figured out the exact details. Nothing crazy though.

415" LS3/L92 based motor could be done rather economically and turn over 500rwhp. I am interested in this build up and enjoyed watching your first build.

What kind of gas mileage did you get on your efi 502? and what gears did you have?

Strokers are OK, but I am not a big fan of how far the pistons come out the bottom of the sleeves. Little scary if you ask me. My power goals are fairly conservative, with a target of 430-450rwhp. The more I play with cars, the more I like stock parts.

I got about 15 mpg with the 502 with 3.73 gears, 28 inch tall tires, and .68 overdrive. I expect to get 23-25 with the new combo.

Welcome Andrew, Sweet look'in Goat. Let us know about your progress. I also Have an Impala SS. Mine's a 96 black cherry. I'll never part with it. It's a great car.

Thanks for the info. I assume you still have the Ls1 Rx7?

GM LS3 6.2L crate engine (P/N 19201992) based on the corvette is like 435hp stock... With headers and maybe a cam you should have 450+ driveable HP... Put a T56 6 speed behind it and you'll get good mileage too.. at least double the 502....

Its always cool to see you working on the GTO Andrew!

(Deep down inside I still want to see a Poncho motor in there, but I get the LS thing...)

The RX7 was dismantled and parted out to fund the latest rounds of upgrades to the GTO and to pay off some debt. I ran a best of 10.95 with it. Running 10s was my goal.

I'm keeping everything the same from the bellhousing back. The T56 requires extensive mods to the trans tunnel that I don't want to do. The Richmond is a nice trans.

Today I dropped off the big block at its new home and picked up an L92 truck engine. The big ugly truck intake will need to go, as will the water pump and balancer. I also picked up a take out LS7 cam, LS7 valve springs with retainers from Jeff Schwartz. I will post pictures of the new engine tomorrow.

Are you planning on keeping the shaker hood? Sorry to hear about the RX7.
