magicmustang Posted August 3, 2019 Share Posted August 3, 2019 (edited) Well, it's has been a while since I looked at some of my old Pro Stock builds. Took out my Grumpy's Toy Vega and had never realized that when I build it in the early 80's that MPC had made several mistakes. The engine was a 350 ci Chevy with an auto trans and Holley 4500 carbs, all wrong. Found a nice 302 (331ci) engine with a 4 speed trans in a '68 Camaro Z/28 kit, added a correct high rise manifold with dual Holley 660 cfm carbs. Found a good set of proper headers. I think it looks better now. Pic shows rebuild with original kit engine next to it. I guess I need to go thru my other Pro Stocks and look for other mistakes.

Force Posted August 3, 2019 Share Posted August 3, 2019 (edited) I'm not even sure the kit engine is a 350 because all Chevy Generation 1 small block engines looks pretty much the same on the outside. This engine looks more like a 396-454 big block if you go by the evenly spaced exhaust ports and the valve covers, the intake manifold is not Chevy at all as the intake ports should be siamesed even on the big block, so it looks more like Ford or Mopar Hemi. Your engine choice looks a lot better and more correct and you did a good job. Edited August 3, 2019 by Force Quote Link to comment Share on other sites More sharing options...

Force Posted August 3, 2019 Share Posted August 3, 2019 Well a small block has four bolts holding the valve covers, two on top and two on the bottom...the kit covers looks to have three on the bottom...even that is wrong as a big block has four on the bottom and three on top. MPC hasn't been known to do absolutely correct kits and this one is not an exception. Quote Link to comment Share on other sites More sharing options...
Snake45 Posted August 4, 2019 Share Posted August 4, 2019 Very nice rebuild work! Your new engine looks MUCH better. Wouldn't it be great if Round 2 could reissue this one? Well done and model on! Quote Link to comment Share on other sites More sharing options...

boss 302 mustang Posted August 4, 2019 Share Posted August 4, 2019 MPC took a lot of liberties with their engines.......the original engine does look like a rat. The "firefighter" Mustang reissue like the original Ford kits has a windsor engine, not a Cleveland like the real ones did as well. Quote Link to comment Share on other sites More sharing options...

Mark Posted August 6, 2019 Share Posted August 6, 2019 The engine in the original kits is a big-block, the first MPC Vega with it was the Street Funny in '71. The Jenkins kit had the gutted interior but still had the stock chassis with molded-in exhaust detail and radiused rear wheel openings with no flare. The '74 Bruce Larson kit had the modified chassis and bigger wheel tubs in the interior, same hood (incorrect for '74, the scoop didn't work with the later front end), same big-block engine and automatic transmission.

Muncie Posted August 6, 2019 Share Posted August 6, 2019 Love it, your changes are a big improvement over the stock kit, well done - it reeeally looks good Quote Link to comment Share on other sites More sharing options...
dragcarz Posted August 7, 2019 Share Posted August 7, 2019 Wow, I’ve had this kit on the back of my bench for years. I’ve always wanted a accurate Grumpy’s Vega. I’ve corrected the rear wheel openings, and recently discovered the Chevy Monza kit has a more accurate front suspension. Yours looks great, a much needed inspiration for me. I for one really appreciate you guys posting you projects and finished builds. It makes me want to get back to the bench. Quote Link to comment Share on other sites More sharing options...

Oldschool4x4 Posted August 8, 2019 Share Posted August 8, 2019 This is a question and not a jab, shouldn't the engine be black? Quote Link to comment Share on other sites More sharing options...

Grumpy was well known for painting his engines black, but I don't know if he was still doing this in 1974. Will have to look in the book tonight.

geemoney Posted August 8, 2019 Share Posted August 8, 2019 looks great!! so great! I have the Larson car somewhere... I remember being disappointed about the rear fender openings. Quote Link to comment Share on other sites More sharing options...
OneTrickPony Posted August 8, 2019 Share Posted August 8, 2019 Da Grump could have been running a big block and automatic when match racing. That was all "run-what-ya-brung!" Quote Link to comment Share on other sites More sharing options...

Yep, but I would have to disassemble it again, so I'll live with it. I believe the engine bay was white and the windshield wipers were deleted, too. Oh well, maybe on the next rebuild!

Okay, took it apart again and painted the firewall white, the wheel wells and radiator wall aluminum. I like the red engine so I'm gonna leave it even though Grumpy painted them black.
