Here are a couple of photos of the yellow valve covers that you referenced. Those are the problems with resurrecting these old engines, the work and money to bring them into specification so that they can be operated on the pump gas that is available to us today. Most modern engines, with the lack of Tetraethyl Lead in today's fuels, will use hard valve seats that are pressed into the heads to prevent valve recession. Also, 1960's engines had the advantage of Tetraethyl Lead in the fuel to prevent valves from receeding down into their seats. Compression ratios over that will tend to detonate on pump gas. Today, the highest recommended static compression ratio we can safely run with iron cylinder heads is about 9.5:1. In 1960, we had high octane pump gas available everywhere, so running 10.2:1 static compression ratio was not a problem. V-8 with 360hp, 10.6:1 compression and dual exhaust with special header-type exhaust manifolds, aluminum intake manifold, dual-point distributor and Holley four-barrel carburetor In the Square 'Bird's last model year, 1960, Ford offered three Thunderbird engines: the reliable old 300hp 352, the 430 and an Interceptor Special, a 352-cu.in. I don't know the years but some square birds had the 430 lincoln- merc engines.
My son had a 60 bird with a 429 TJ the guy had knotched the fender apron for the PS clearance. some of the thunderbird police interceptor special engines came with 60 over pistons and would ping unless you ran w105 octane gas. and an aluminum intake will save a lot of weight on a FE. If you do a rebuild keep the bolts back into the right holes there is a spot on the front of the block where a bolt too long can push against the cyl wall, causing a hot spot. they look the same most engine parts work. Or maybe there are some other upgrades I should make as part of the rebuild?įe edsels and merc used different colors. If its the original engine I think I prefer to rebuild it in its current displacement, but conversion to a 390 is also apparently common.Īny other comments on whether it makes sense to rebuild the 352 Thunderbird Special engine? I've always considered them the low end step-child engine of the FE series, but this one seems more interesting. It had 10.2 compression and a Holley 4 barrel, but but I can't find out whether it had different heads or any other special components. The 1960 FE 352 4 barrel Thunderbird Special engine was rated at 300 HP, but I don't know how well that worked in a car this heavy. Would these have been stock engine paint colors in 1960? However, I'm used to seeing the later FE air cleaner and valve covers painted with Ford blue colors. This engine has very pitted cream/yellow colored valve covers, and a repainted cream colored air cleaner. I'm looking at a 1960 Ford Thunderbird that appears to have the original 352 4 barrel engine (it starts and runs).
