how many people run big blocks in 4th gen f-bodys.how much mods are needed to make it fit and can you actually work on the engine in the car?Do they make headers to fit or is it all custom?What kind of ignition system are you running.Any info would be great. Thanks.

I know that there are a couple of guys that started with an F-body and made high-end drag cars out of them with big blocks. Search the web, you might find the page.

i know somebody that took GM's latest big block, the Mark IV I think? the 7.4l fuel injected motor they put in the big trucks into a corvette <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

I have to ask why you'd do this. You can have a 427" plus LSx motor that is lighter and has equally as good if not better heads.
You can make a 454" LS1 also <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> .

While you can get the same displacement as some big blocks, you can't get the same amount of airflow from the heads. I'm willing to bet that even race-ported C5R heads won't flow as much as some equally ported BBC heads. Once someone improves upon our head design, you might be correct.

As for the vette with the big block I know him from friends I race with its a 530 ci motor carb motor on the bottle. He just gernaded that this past season.A little juice happy.Why I want to do this is, I run sb right now but I use to run big blocks in my chevelle when I had it and never had any problems didnt have to wind the motor to 10 and it stayed together alot better less to maintain with no power adders. I could get 850 hp out of the motor without alot of money and didnt have to inspect it every season and could still get more out of the motor if I wanted. I could stroke the sb but how strong and long will it last compared to the bb. Its just a opinion debate. I just wanted to see how much work I am going to have to do to wedge this motor in there.

Is the zL-camaro a big block. I saw a Car and Driver TV clip, and the announcer said it was a big block with over 700 hp.

Yeah, the ZL-1 is a 502 I think. I have an article from about 6 years ago that chronicled the swap into an LT-1 camaro. If I recall correctly, the battery went to the rear, A.C. gone, new engine mounts and k-member modified to lower the engine abit to fit under the cowl. Tons of work that a real good hot rod shop could figure out. Wait! It was a Merlin 502 that was was first put in. At least I'm pretty sure it was. <img border="0" alt="[driving]" title="" src="graemlins/gr_driving3.gif" />

I should have added it is a 98 or newer car. I have seen pics from other events.

It is a good looking car.

As for everyone else talking about having a 427" or 454" stroker LSx motor, I have 1 thing to say. TORQUE. Stock the Mark VI puts out nearly 500lb-ft of tq <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Put a bigger cam in and slightly better heads and you got yourself a real winner...and best of all you DONT have to rev it to 6500rpm to make power like our LS1's <img border="0" title="" alt="[Mad]" src="gr_images/icons/mad.gif" />

well I called the chassis shop and gave him the OK to start getting some Ideas about putting the bb in . I am going to yank the supercharged LT4 out, sell that and my bike . I am hoping theres no regrets. I am not doing it to be the fastest but to have a reliable bracket car. the torque is nice too.

Here's the specs on that ZL1 Camaro that Jon Moss's crew put together:

Thanks neil

The Guy in MY 99TA

There was a 93 or 94 Z28 with a 502 crate motor featured in Super Chevy back in like Sept. of 1999. I think it was in 1999 I have the magazine in my room but it's been through hell. I'll see if I can't get some scanned pics though.

thanks but I have the issue with the 502 502.it doesnt say much about the car other than whats in it.

ZippyZ28

Good luck... I had considered doing it to my 95 Z but decided I would be better off buying a new camaro, I even had an extra 454 sitting around to drop in... Its a TON of work and I hope everything goes well for ya.

It is a lot of work to get a big block in, don't make the mistake of thinking its "just an engine swap"
